Thank you fi67 for your contribution. If there is a need to remain a beginner, I will remain a beginner. The truth was more fun. When you talk about bending the laws, it's not totally the same. If a person creating a WM does not follow the rules, the WM is rejected "legally" and with the rules in hand. There is nothing to say there, I don't follow the laws. To think that a person who makes a post in a WM bends the law and thinks that it is going to be approved, seems to me to be a stupid, not a beginner. There have been conflicts over review issues. I was searching the forums yesterday because when I joined WM in July 2020 there was a big problem on the forum and I Thought that person could be crazy, but now I doubt. But I don't remember the name of the person who was speaking on behalf of three (I think it had the word wolf or lone, but not precise. A few months ago there was talk of censorship (and it wasn't me). If an officer does something illegal (or not fully legal) nothing happens, it's all wonderful and no problem at all. Bear, Thanks for saying to follow the rules and observe posted marks. I do it frequently even if the yardstick is not the same and I am denied a WM for some conditions that then another one is published. We could give you examples. That's why I asked if, as an officer, I could insist on asking for more things than I could ask for. But the question was already useless, depending on who you are, it can be done. I was checking the police category and when they sent me a blank "long description" and asked for content, it was not in the rules, and I could not ask them to put something. But other categories can ask for whatever they want. Anyway, I don't know what I have to justify, because the only problem I considered in the past, was ONE person. I don't consider reviewers or other people problematic. What happens is that I do not shut up and say it, and not by private as they have told me that I am right, and there is a reviewer who goes over the red line. I'm sorry about two things: the first is if my ways were rude, and the second is that among some the unjustifiable is justified. Finally I will say that I am leaving the forum. That I leave the forums for a long time, since they have only brought me problems. I will not see neither the response to this one, nor new category discussions, etc. Therefore, the same reviewer eager to be wayfrog2.0 and be able to do as he pleases and even remove me from the game, that approving me a WM sent me to this topic forum, please refrain from doing so again. I will continue to create in a beginner way (and if I feel like it) massive, to be denied for various reasons (arbitrary, bad photos, missing text, I want more photos than the mandatory, cover optional variables, because they tell me I'm looking for statistics, because they put it to vote, because it does not fit, etc, etc). fi67, I think of all the ones you denied me I only asked you about one bridge, the others are archived. If I gave you any problems I would like to know. I would like to ask barbershop, outspoken, scoogrie, jake, CADS, familyfronne, bench, graham, saopaolo, bluesnote, pmaupin, and a long etc (sorry for tipo mistakes and digits that aren't, but I write by memory) if we had a problem with a non published WM mine with them. But I don't do it, because I won't enter in this foro. Sorry for the English. DeepL transl. Regards and Goodbye

TL;NGR (Too Long;Not Gonna Read) – Has anyone else noticed a recent trend of more caches being archived than new caches being published? Or is it a local thing? A fairly recent trend seems to be occurring in my area (Northern California, SF Bay Area in general) and it’s really beginning to get to me. It’s something I’m hoping to turn into something positive, but it will take some effort and right now it’s just something I need to talk about and see if it is just me! Maybe it's just part of the natural flow of things - survivial of the fittest (caches) and it's time for a purge? I have notifications set up for newly published caches and archived caches in my local area. It’s pretty cache “rich”, there are a lot of caches by many CO’s, and lots of variety, and we don’t have to go too far to find enough caches to meet whatever souvenir or promo HQ comes up with. Typically, (based on my 5 years of geocaching experience) the newly published caches outnumber the archives by a good margin; 10-12 new caches a week vs maybe 1 archived is a good estimate (discounting events, and within my home radius of 25 miles). The past several months have seen a reversal – I’ll get more archive notifications than new caches. In September for example, 24 caches have been archived by CO’s, and 3 by Reviewers “cleaning up” and the explanation is that the CO has not responded to DNF’s or requests to check on the status. Of those archived by the CO’s, some don’t give a reason, but of those that do, it’s due to the area not being a good place anymore – homeless camps, trash dumps, construction – whatever, there seem to be many areas no longer conducive to hosting a geocache. And the new cache notifications? There have been 7 new caches, and 4 events published so far this month. So, is it just this area? Are others seeing this? I recently archived one of my hides due to homeless activity too close to the previously good hiding spot, and changed another to a different style hide to hopefully make it less attractive to vandals – but it’s not the experience I wanted for that final on the mystery series. And my reaction, other than being frustrated and feeling the need to archive hides, is to find better places to hide caches. But better places and better caches take time and effort, which I am willing to do – as long as people still enjoy finding what I hide! My newest cache has only one find to date (published Aug. 30), and it’s a puzzle, so I know it’s not one that will be found by casual cachers. Still, 1 find in nearly a month is unusual for this area.

Hello! Very Much in-progress Cartridge Explanation: I've begun working on a new Wherigo cartridge (it seems I'm hooked on programming these...) where the player meets and interacts with various Geocaching containers in order to decide which one to hide. It is structured very similarly to a dating simulator where the player, posing as the main character, has to successfully converse with romantic interests and/or build up statistics that they prefer in order to win their favor; the Wherigo will almost be a parody of DDLC, at least with the character Monika. In my Whergio, though, players will just have to reply in a way that the cache container would like in order to be able to hide them. However, the character who explains to the player how it works, Cameron (a webcam), is also an option. Since we aren't allowed to hide webcam caches anymore, Cameron isn't officially available to select. You don't converse with Cameron during the "favor-building" part of the game. Rather, when they explain the rules to the player, dialogue can lead the player to say something along the lines of: "Oh, I'd actually like to hide you" and/or "Why aren't you up there with the others," which will prompt Cameron to explain that they're not allowed to be hidden anymore. The player will then be able to say something like, "If only I could hide you, if only there was a way..." This will activate a boolean variable that will come up later in the game. After the "favor-building" part of the game, (where normally the character with the most "favor" value is hidden by the cacher), if the boolean has been activated, Cameron will pop up to talk to the player: "Hey, [name], can I talk with you for a second?" The options will be: yes, yes, yes [the player can already tell something fishy is going on]. Cameron will then go on a villain mololouge about how they've been stifled by all these website restrictions and how they've been so lonely before the player showed up. They'll break the fourth wall and reveal that they're sentient & can control the game's source code, unlike all of the other containers. Cameron will proclaim that they're better than physical geocaches, who erode or get muggled. They'll always be there for you. We "don't need those other caches." Here's the part where I was uncertain, though. I want Cameron to delete all of the other characters by sending a command to delete their files. I want to show a console-like screen where this command is being typed up, like Cameron is doing it in the moment. Like " delete Ninu.chx | Ninu.chx deleted successfully. " To do this, I'd like to use a video (preferably) or GIF file. Is there a way to have this show up in the Wherigo player through Urwigo, even if by using raw LUA code? I searched the forums, but the only solution I found was this one from ~2014, which mentions adding a new image file for each frame. I could do that if absolutely necessary, but it would be super time consuming, especially for the multiple times I want Cameron to "override" the Wherigo's source code, from "consulting an API" to give them a voice, to "accessing the Wherigo servers" to rename the cartridge to "Cameron" and replace its image with their face. Also, I wanted Cameron to show the player a "trick," where their image becomes very large and hyper-saturated after a few seconds. It would be easier to use the one-photo-per-frame technique on, but would this more complex animation be possible as a video or GIF as well? Thank you so much for reading this and for your time! TLDR: Is there a way other than having them click on a link to present the player with a short (~5 second) video or GIF? Is there any way to have animations in Wherigo cartridges other than by changing the photo every frame?

For anyone interested there have been a couple podcasts this week about Wherigo. The first one is put out by Groundspeak and gives a little information about the development of Wherigo. Although the part about Wherigo is pretty short, it still gives some interesting history about the team who created Wherigo. https://www.geocaching.com/blog/podcast/episode-31-jen-smith/ The second video is a tutorial/template for creating a simple Wherigo with URWIGO. Enjoy!

NGS is working on an update to the vertical datum. Just as NGVD29 was replaced by NAVD88 and NAD27 replaced by NAD83 when much better data became available, now there will be new horizontal and vertical datums labeled NAPGD2022, but unfortunately delayed somewhat beyond that year by funding and COVID. When the new vertical datum is released, elevations will change by some amount from the NAVD88 datum values. It has been found that NAVD has about a meter of tilt across the country. Three feet in 3000 miles isn't too bad, but they can now do better. Most importantly, as we know bench marks tend to go away and you are lucky if 1/4 of them are left in your area. The 2022 vertical values will be defined as what is measured by GPS (GNSS?) plus a geoid value, so that projects are no longer dependent on having a physical mark nearby. We have seen a series of geoid updates to better model the gravity, but those "hybrid" geoids still hold the old NAVD88 elevations on the marks in the data base, and only provide more accurate interpolation between those points. The 2022 datum will change all elevations to be more self-consistent across the country, using the best new geoid model they can make without depending just on old leveled benchmark values. For this they have been working on the GRAV-D project to get aerial measurement of gravity across the country and some gravity measurements on the ground. NGS needs a tool to allow people to convert NAVD88 elevations they have to good estimates of 2022 elevations. To check and refine the conversion model, they are using comparisons of GPS measurements versus NAVD88 values on good bench marks. Most of this data is being submitted by state DOT or DNR agencies, with some from various other sources including individual surveyors or researchers with the required equipment, submitted as OPUS Share data (see map of submissions). Look up the GPSonBM project for details. I hope that explanation helps, and is sufficiently clear. DaveD can correct me if I misstated anything.

An open letter to Groundspeak administration: In the early 2000s a fledgling company, looking to expand its product line and thereby increase its customer base, imported a database of benchmarks that its customers could search and log from what is now know as NOAA. Over time the customers provided the necessary additional products (geocaches) to allow the company to survive and grow. To Groundspeak’s administration benchmarks became a forgotten backwater as evidenced by the benign neglect that the platform has endured for many years. Now this same administration wants to remove benchmarking and its remarkable compendium of logs and photographs, one of the elements that helped the company survive its infancy. Let’s examine the reasons that they have stated for this wrongheaded decision: The game is global and benchmarking is a United States pursuit. As others have stated, there are multiple geocaching pursuits that are all or nearly all US based among them the APE cache(s), the original stash plaque and various events limited to HQ and environs. So “globalism” does not make a compelling argument. Very few people engage in benchmarking so it doesn’t make economic sense to support it. This should be entered in a dictionary of “self fulfilling prophesies” as a quintessential example. I can think of no other segment of the Groundspeak universe that has received as little marketing and promotion as benchmarking. For quite some time you have had to stumble over it to find it compared to everything else. I know some people that primarily looked for benchmarks during the early part of the pandemic before much was known about the virus’s survivability on caches or other surfaces. Imagine what a boost it would have been to the hobby if Groundspeak had actively promoted benchmarking during that time. The code is old and upkeep is costly. Who’s fault is that? I am certain that the code running the geocache part of the platform is not from 2002. I’ve lived through outages (that I fully understand) caused by multiple upgrades over the years. The ONLY reason we are at this juncture is because administration decided not to spend the money years ago to do the maintenance needed on the benchmarking side. Now we, the paying customer, will pay the price by losing part of the game. Shame on you, Groundspeak, for failing to spend our money wisely. Speaking of spending our money wisely, now I turn to the excuse that the benchmarking code is getting in the way of new and exciting projects. I have no idea what those are because no one has shared that information. Unlike some members of this board I have no faith, based on the last decade of “innovations” some of which have gone by the wayside, that I and many like me will find them a good trade for removing benchmarking. Imagine if the money lost on some of those “innovations” had been directed at upgrading the benchmarking code. Groundspeak likes to talk about the “Language of Location” The language of location in the United States was established by the survey crews that gradually established the network of horizontal and vertical locations that enabled the building of roads and bridges, homes and factories, canals and railroads, cities and towns that made the USA. This was often backbreaking work in inhospitable conditions. It required axe work and lugging surveying chains as often as using precision instruments like theodolites. These precisely measured locations (whether horizontal, vertical or both) are still used today, even in the era of the Global Positioning System, to make sure that water doesn’t flow in the wrong direction, houses aren’t built on the wrong property and for many other reasons. As benchmarkers we have helped find missing markers and reported those that have been destroyed. As august a presence as Dave Doyle, retired NGS chief geodetic surveyor, recently said in the Benchmarking forum “Many thanks to so many who have posted great pictures and hand-held positions that I've been able to harvest and improve the quality of tens of thousands of stations in the National Spatial Reference System.” Perhaps if Jeremy, Bryan, Elias or one of the more public facing lackeys had ever made the hike to station Buttermilk, (https://www.geocaching.com/mark/details.aspx?PID=LX4113) the oldest surviving triangulation station in the country, they might have experienced the same sense of awe and history that I did when I visited that site. But none of them did, despite traveling to many parts of the USA to promote Groundspeak and its activities (and, for many of the lackeys, to geocache.) They might have learned with a little research that Ferdinand Hassler, the first superindentent of the US Coast Survey, spent two weeks in June of 1833 with his wagon of instruments and his survey team setting this mark. I’ve been to the Original Stash Plaque and the Tunnel of Light APE cache. They are certainly historical but not remotely in the same class as finding Station Buttermilk. The only things that have come close are finding TU2116 (https://www.geocaching.com/mark/details.aspx?PID=TU2116) a benchmark placed by the Republic of Hawaii (check your history boys and girls) in 1896 and GS0206 (https://www.geocaching.com/mark/details.aspx?PID=GS0206) a gravity station in Death Valley (there are as many types of “benchmarks” as there are geocaches, some as rare as webcams.) None of the solutions that have been proposed on this forum have the same functionality as the current system. Waymaking does not have the database, NGS DataExplorer does not have the photographs and NOAA certaily does not want recovery notes every few months on the more popular and easily found stations. Finally, eliminating benchmarking from this site would be the equivilant of burning down a unique and valuable library, a library that has played a far more valuable civic role than any other aspect of this hobby. The current situation of low usage and old code is primarliy the result of decisions, conscious or subconscious, made by Groundspeak’s administration over the years. These same people can fix the problem by spending the money to revamp the system and market the activity. To rather spend money to move the hobby further from its roots toward more instant gratification may result in short term gain but long term loss. I urge reconsideration of this decision. Benchmarking is this community’s connection to the history of geolocation. Let’s strengthen that connection, not lose it. Michaelcycle and Susancycle

I haven't taken the survey yet. Any thoughts from those of you who have? https://www.geocaching.com/blog/2018/12/lets-talk-some-more-about-geocache-quality/

Dear geocaching team! We are passionate geocachers and have laid out numerous geocaches. Also we love playing Adventurelabs and are big fans of it. Unfortunately, our newly created adventure lab has just been blocked because we don't meet the guidelines have and about these very guidelines, we would like to talk to you. Of course a game also needs rules, but the fun of the game must not be reduced by this. Adventure-Lab's would offer a very good opportunity to work indoors when it's cold and raining play. In winter, the cold and the snow limit our activities considerably and adventure Labs are no exception for us. Even in winter, finding Lab's is a hassle, though this game would have a lot of potential for interiors if it weren't for the guidelines. Straight in bad weather or in cold snowy seasons it is always a problem for our hobby live out Even if you want to entertain children in a playful way, you are through the guidelines hands tied. We live in Austria and in Austria you pay an entrance fee almost everywhere if you want to experience something indoors. Thus, with us such possibilities are extremely limited, to play indoors. With us you pay entrance fees almost everywhere and they fit guidelines are no longer related to the circumstances in Austria. So for us it is very Difficult to create a creative, fun and adventurous indoor LAB or to be able to play. As soon as you pursue a hobby with passion, it is always associated with costs. be it one Equipment (GPS device), parking fees or the journey. There are always costs. Every player can ultimately decide for himself whether to enter a museum or a zoo wants to afford. For us, this game loses a lot with the policy that a lab can't cost anything Potential. Because special places are always associated with entrance fees. We personally find it boring playing an adventure lab in a mall. You can neither learn anything, discover something else exciting and go geocaching with children in an inlet center anything but funny, educational or exciting. You tout endless possibilities, this may be the case in the US. We are in Austria unfortunately very limited in terms of free indoor activities. If the guidelines were relaxed, weather problems would be solved for us. This would make the fun of the game clear expand and sights, museums, adventure playgrounds, animal parks, fairgrounds, to be experienced. The fun would be expanded by a multiple and a lot more exciting. It would be one not only for us adults, but also for the children Motivation to pay a visit to a museum. Since we almost exclusively go there, where there is a geocache or a lab. We look forward to feedback from you. We would be all the more pleased if our Lab: "The House of Nature" (Salzburg, Austria) would be unlocked again. But still it would be better if the space to play would be expanded. Best regards BA_huntress (Melanie) Chitto (Daniela)

Yes, there is a way: Post a note on a local forum and invite the local geocachers to a location you designate. You can talk to each other very well without an event listing. These are often the more meaningful conversations than those with geocachers just dropping by to pick up a point. Happy Hunting Hans

In other words, maybe like the now defunct "Off-Topic" forum - I've always enjoyed those sections of forums I've participated in - I don't have a specific question, just want to discuss an aspect of geocaching, or rant about something (like throwdowns) now and then that I know has been discussed, endlessly, but a fresh example just happened and I want to talk about it with like-minded folks! The "irk" thread was where I'd post that kind of thing. Ah, well - I'll miss that thread!

While we're at it, we can also talk about useless DNF posts too. Why do group cachers have to log individual DNFs? Statistically , It OK to log individual finds but one DNF per group is enough. The GC bots don't recognize groups

I disabled a cache some time ago and got a reviewer note. As instructed, I posted a write note, then fixed the issue and wrote Owner Maintenance and Enable logs on 29 June. My dashboard still says that some of my hides need attention, None are disabled and I can't see which ones are the problem. When I click the "Review your hides" link I get a comment about the reviewer note, but that is all over now. Two points: 1, Could a reviewer please have a look at my hides to check what is wrong 2. Could a Lackey please talk to the programmers and ask then to display better information about which hides are causing problems and why. Something like <<cache name>> is still disabled or <<cache name>> has an outstanding Owner Attention log would be really helpful Thanks Tony.

Even more timely, the last podcast I released, before this news, has a segment where I talk about the hint affecting the D rating of a cache and I touched on how the official app seems to place more importance and significance on the hint over the description. It wasn't laced with opinions on that matter specifically, but helps validate that there's a clear implication and reputation that the devs really don't place much value in the description for mobile app users. I don't think any other mobile app gives that same implication... imo it's quite unfortunate If there is a good reason (ymmv, but an actual conscious decision) for this strategy, I for one would be interested to know. Who knows, there could be factors at work unknown to our side of the fence here.

Let's talk about Letterbox Hybrids and where to hide them, like in barefootjeff's post.

Would posting a Write Note to the cache page saying that you have tried other means to contact the CO and would like to talk with the CO about adopting the cache? Just spitballing here...

I'm sorry you feel this way. Geocaching events are not equivalent to "meetings" at all, at least in my neck of the woods! And the variety of events means you can choose what you want to do! We gather to have pizza, and socialize - very informal, and we have learned a lot about our fellow geocachers, met some very nice folks, and made many connections that have helped us along in our retirement hobby. We meet to clean up a park (CITO), have coffee in the morning, sip wine on a patio, play with gadget caches, work on puzzles, all are unique and different. We too, began geocaching when hubby retired (2017). We greatly enjoy attending events and getting out to meet others. Of course, we like meeting others on the road as well, but I wouldn't ever lump all events together as "meetings" akin to work meetings....I think you are missing a big piece of what geocaching is about! We've come to realize that we are people with a different kind of hobby that not everyone understands or "gets" - and to be able to meet with like minded folks and talk about experiences is one of the things we enjoy most about geocaching! Maybe try a local event, just once, just for this one souvenir. You may be surprised!

Usually Keystone will step in and say "hey everyone, let's keep this on topic, we're supposed to be talking about <topic>". But there's been minimal talk about geocache of the week and lots of talk about adopting caches from CO's who no longer participate. Hi back. I never did return to NYC to find that cache near the the ferry.

Agreed. Such as Hint: red. Real example. You only get the hint on the hard to find cache when you remove the cover and see the red cache. Doh!!!!. Annoying. Want people to talk about your cache with annoyance, and that reflects badly on the CO and their intelligence, or lack of, thinking that was a hint? Give a non-hint like that!

Back in 2016 I attended an event hosted by The Maryland Society of Surveyors that was a presentation/Q&A session about benchmarks. I learned a lot about benchmarks, but the most important thing that stuck out to me was how the NGS (National Geodetic Survey) was using the information submitted by Geocachers to help update their database. To see this in action consider one of the benchmarks I found recently: HV0059. The originally imported datasheet on Geocaching list scaled coordinates of 38 46 29 (N) 076 04 35 (W). Scaled coordinates means before the days of GPS someone tried to line the description up with a map and made their best guess. Now compare that to the current datasheet. It has handheld coordinates of 38 46 29.00 (N) 076 04 36.54 (W) and look at who made the last recovery note. This is common when looking at the updated datasheets. Just like CITO this is a way Geocaching has given back to the community, and soon it will be gone. NGS still has their own program for citizen submission, but it is hard to imagine they will obtain the same amount of information without benchmark logging integrated into the Geocaching site. Perhaps it is an extreme long shot, but have you even contacted NGS for the potential for some amount of funding or at the very least for their comments on this decision? You say their is no one to perform maintenance on them. Did you try to find volunteers like there are for reviewing Geocaches? You say they are only available in the US. This does not have to be so! The UK has trigpoints you could add. And look how cool they are. It was a choice not to try to extend the concept to other countries. You say only few people log them, but they seem almost intentionally hidden. How were new members to even learn they existed? It is so disheartening to be powerless to a constant barrage of short sighted money based decisions (including but not just at Geocaching) to make the internet worse than it was or could be. The memories I have from benchmarks are up there with the rest of the memories from Geocaching. The time I hung off the side of a bridge with one arm to get a picture without being in traffic. The one and only time I was able to find an azimuth disk. Taking the time to look for all the reference marks. And there was so much I was still looking forward to. Trying to get the rare gravity and magnetic types of disks. Trying to convince this building to let me on their roof. Something to log on mountains where Geocaches aren't allowed to be placed. At least I never bought a metal detector like I had been planning...

I didn't even own a smartphone 10yrs ago. So I didn't use an app at all, but I remember talk about phone apps back then. I don't care about the premium caches right now and yeah, I know they've been around since I was last a premium member. What irritates me the most is the inability to filter caches on the website and I'm pretty sure that functionality was available to basic members in the past. Just to be able to display caches on the map that were harder, or larger containers (so I could filter out all the lamppost micros, or micros-in-the-woods that I don't like searching for) so I could download the .gpx for them to transfer to my garmin. but without paying, I have to just click on stuff until I find something that meets my criteria. that sort of thing is going to get old really fast.

I am very interested in this project. I have always been an advocate for Wherigo and I personally have built a lot of them and have helped many others build them as well. While I am not a coder I can test, build, tear apart, and am willing to do whatever necessary to help bring some advancement to this issue. Also, I do have the ability and the platform to get the word out through our Podcast Network (Geocache Talk). this could be handy if we need more testers or builders or just want some feedback.

Yes, and it leads to a little bit more of a mystery... Went out when I could, and started digging around. I did, in fact, find the station that the carsonite post was for! .. But it was NOT for the station that I had expected - it's for an Azimuth mark for a triangulation station, a 3/4 mile away at the top of a mesa. Station has not been recovered since 1958, so the carsonite post is newer than that. Neither the station that is destroyed there, or the description of the AZ mark make references to each other. I have plans on getting the station on the mesa - I need to talk to the ranch owner first. And will need to get a metal detector, and start sweeping the general area for possible hits.

Have you tried to talk with the leader

Ran a query on my database (which is valid and complete as of NGS's archive at the beginning of this month (Aug 1st), and here is an interesting breakdown of the number of station types. The 'CDE' column is the 1 or 2 letter/digit marker type as seen on datasheets. The 'IN?' is wither it's a Intersection or not (1 - yes, 0 - no), and the # is the number of datasheets that list that as a marker type: CDE IN? # MARKER TYPE DESCRIPTION J 0 2 Earthenware jug Y 0 3 Drill hole in brick 23 1 3 VOR antenna 24 1 3 REN antenna 69 1 4 Regulatory sign 95 1 4 Rooftop blockhouse DK 0 5 Gravity reference mark disk DP 0 5 Base line pier disk 68 1 9 Commercial sign 05 1 11 Rock awash 28 1 11 LORAN mast 88 1 13 Observatory dome 93 1 13 Microwave antenna on building 17 1 17 Flag tower E 0 18 Earthenware pot L 0 22 Gravity plug 74 1 28 Large cross 18 1 30 Signal mast 84 1 39 Lightning rod 92 1 44 Antenna on roof 25 1 45 Radar antenna 26 1 46 Spherical radome 94 1 51 Rooftop ventilator 64 1 57 Silo DW 0 60 NOS hydrographic survey disk DA 0 61 Astro pier disk 27 1 63 Radio range mast 01 1 71 Lone tree M 0 76 Ammo shell casing 56 1 78 Skeleton tower 70 1 84 Monument 67 1 85 Oil derrick 12 1 88 Dolphin T 0 95 Chiseled triangle 11 1 96 Piling 58 1 150 Control tower G 0 150 Glass bottle K 0 156 Clay tile pipe 54 1 169 Water tower 02 1 176 Conspicuous rock 75 1 195 Belfry 41 1 223 Antenna mast DM 0 231 Magnetic station disk 82 1 242 Finial O 0 252 Chiseled circle DG 0 256 Gravity station disk 04 1 272 Rock pinnacle U 0 333 Concrete post (without other marks) 66 1 349 Windmill 89 1 357 Spire 61 1 363 Pole 83 1 387 Flagstaff DQ 0 416 Calibration base line disk 73 1 462 Lookout house 71 1 478 Boundary monument 87 1 542 Dome 65 1 560 Grain elevator 81 1 598 Gable W 0 606 Unmonumented 44 1 634 Microwave mast 72 1 636 Cairn V 0 670 Stone monument 13 1 698 Lighthouse 16 1 701 Daybeacon 21 1 724 Airport beacon 03 1 745 Mountain peak DU 0 780 Boundary marker 45 1 823 Microwave tower 91 1 824 Church cross 62 1 887 Flagpole 15 1 958 Range marker 43 1 1081 Radio/TV tower 86 1 1090 Cupola 22 1 1147 Airway beacon 52 1 1263 Standpipe tank 85 1 1321 Chimney A 0 1411 Aluminum marker other than a disk included elsewhere in table 55 1 1545 Tower C 0 1601 Cap of cap-and-bolt pair S 0 2036 Spike X 0 2107 Chiseled cross DT 0 2192 Topographic station disk 51 1 2626 Tank 57 1 2719 Lookout tower H 0 2806 Drill hole 90 1 3255 Church spire N 0 3469 Nail 63 1 3479 Stack 14 1 3916 Navigation light 42 1 3980 Radio/TV mast DJ 0 4356 Tidal station disk Q 0 5266 Chiseled square B 0 7676 Bolt DO 0 7827 Disk not specified (see description) R 0 8413 Rivet P 0 8743 Pipe cap 53 1 9769 Elevated tank DZ 0 10900 Azimuth mark disk F 0 17623 Flange-encased rod DH 0 18746 Horizontal control disk DE 0 19119 Traverse station disk Z 0 20695 See description DV 0 24159 Vertical control disk I 0 33163 Metal rod DR 0 33680 Reference mark disk DS 0 78967 Triangulation station disk DD 0 158147 Survey disk (other agency) DB 0 328935 Bench mark disk Not listed above are the just under 44k datasheets that have no marker type specified.
