Early this month, Stompy&Stampy asked if it was possible to create a game of Tetris using Wherigo. While it is possible, the player apps need to be updated for it to be feasible. Most player apps require you to click somewhere else to refresh the map. That alone makes this a difficult cartridge to play in an app. I have also not tested this in an app long enough to see what happens if we get 150 active zones (blocks) shown in the well. The good news is Webwigo, the online emulator, is really awesome with this cartridge. It works fabulously. If you want to play it, go to WGV6 on the Wherigo Foundation site and click "Play In Emulator" in the column to the right. You'll probably need to be logged in for this. I included instructions in the cartridge. In short, four zones appear around the player in a D-pad formation. The left (west) zone will move the falling tetrimino left, right will move it right, up will rotate counterclockwise, and down will rotate counter-clockwise. There isn't a zone to move the tetrimino all the way down, so you'll have to wait for it to fall. I created an eventing system in the cartridge so a falling tetrimino is not deformed if the player tries to move it the moment the code makes it fall by a line. I'm also enjoying Lambda expressions, which I barely got into during my Cacher Pursuit arcade cartridge. I implemented the bag system. I did not implement gravity fill for clumps after a line is cleared as it would have been quite a bit of math to figure that out (and I was lazy, possibly because I received the Oculus Rift and have been playing around with it). Please note this cartridge is not currently open source. I own the code that runs this cartridge. I will release it as open source after the player apps can play this and I've placed a few Wherigo geocaches to get the general population to test this for me. After that, you can make cartridges based on this. Until then, I'll actively archive anyone who rips the source code and makes their own Wherigo geocache. So please play nice and give the player apps some time to update and testing to commence. I don't want to release a cartridge that will give people a hard time. So, questions? Comments? Fun idea? How long did you play the cartridge in the emulator? Did you have fun? Let me know!

I just finished hiking the Zion NP Angels landing. The most dangerous hike so they say...I wanted a level 4 stat. I don't understand how a cache so death defying is a 4 when it appears I have 2 4.5 caches already and don't know what they are or remember them. How do I find out? I realize the terrain rating is up to the co, and a lot of reasons why they choose what they do. Last summer I climbed to high camp at olympic village in Lake Tahoe, on a broken foot (didn't know). The terrain was with the assumption one took the ski lift. it was a 1.5 rating and took me hours and was very exhausting physically. There should be a way to get permission for the alternative. Anyway, I want to know which caches I got were 4.5 and I could have fallen to my death on a 4. :} thanks

First background on my current physical abilities: Last June/July my left knee started bothering me. I have no idea what I did to it, I did not turn or twist it, hit it on something, fall on it, etc. It started hurting to the point of having limited mobility. I after being prescribed an un-loader brace, going to the orthopedic specialist, having an injection, x-ray and an MRI, which only found arthritis I had it scoped. The Dr. found and fixed three things, cartilage tear and a meniscus tear both. Also found was plica tissue which should have disappeared before I was born or at the latest when I was still a toddler, I was 43 at the time this was happening. The scope was in August of 2015 and after PT I still needed the un-loader brace for activities such as riding bike, mowing lawn, etc. Summer ends, fall comes and ends and I hang the bike up for the year but still need the brace for tings such as clearing snow from driveway. I needed another round of PT due to knee starting to bother me again. this is when I was told I have vein variscosity in the left leg and should get it checked. The new year starts and my wait for a while to see another doctor. In early Spring my knee joint is as good as it is going to be for a while but below the knee the pain and swelling is getting worse. I see a vein specialist. After wearing compression socks I have the procedure to close the varicose veins. The final treatment for which was today. While the varicose veins were and the problem with the knee joint are and were completely unrelated the swelling from the varicose the veins does affect the knee when it occurs below the knee joint because of things like the law of gravity. After enduring all of this with the knee and lower leg I am feeling a lot better. I have since stopped using the brace and my mobility is a lot easier than it was 10 months ago. With that boring story out of the way I have noticed when it comes to cache listings there is an indication of the terrain and whether or not is handicap accessible. I started geocaching when I was still using the brace, in fact the very first time out I had to wear it. I am glad I did, without it I would not have been able to do what I did to grab the cache from a hiding place. Even with this I was still very sore when I got home and took the brace off. My physical disability was very minor by comparison, not to mention temporary. I have seen people with permanent disabilities that are more mobile and capable than some would give them credit for. I have seen people go places in wheel chairs compared to some who have full mobility without the help of an aid that will not even do so on foot. People with disability's or limited abilities no doubt only do what they know they can. Do you know of anyone who geocache's with a physical disability and even with a mobility aid and does not let it stop them regardless of the terrain rating or if the location is not suitable for say wheel chair or handicap access? Have you ever seen anyone geocache like this?

In BuckBrooke's collection of finds of benchmark agencies, there are 5 examples of gravity stations. one for a state. Besides horizontal control stations and vertical control stations, there are gravity stations and magnetic stations. Hopefully you can go back and get a picture. Gravity stations and magnetic stations are rare and therefore interesting to us benchmark hunters.

The epoch is extremely important over here in California where we have significant velocity caused by plate tectonic motion and occasional large earthquakes. I find that HTDP datum and epoch adjustments of existing CSRS 1991.35 HARN/HPGN monuments don't give me the same warm and fuzzy feeling that a new current measurement does. GEOCON adjustments are even worse. I'm talking about differences of two or three tenths of a foot when comparing an HTDP datum and epoch adjusted position to a newly measured position (24 hours of raw data static post processed through OPUS Projects using either rapid or final orbits). I gather HTDP just isn't capable of that level of accuracy. I've been playing around with OPUS Projects lately. I think it's the bomb. If you haven't already done so, sign up for one of those online OPUS Projects webinars so that you can get access to OPUS Projects. If you set it up correctly it does a better job than either OPUS or OPUS-RS. I haven't seen you post anything here yet about vertical height datums such as leveled NGVD29 vs. leveled NAVD88 vs. GEOID12B or the new gravity model based one coming out in 2022 or whenever.

Get a load of the local list on this one. It was used on the same date as L 61. My PS was on this one. It was a dandy to setup on. The were at edge of a breakwall dropping off about 30 ft to Lake Michigan and had to rig it to setup a tripod. The NGS Data Sheet See file dsdata.txt for more information about the datasheet.

To make things a bit easier when you are just getting started you could try looking for benchmarks that have already been found by other benchmarkers. Also look at the benchmark page and make sure the Coordinates for the horizontal position are adjusted. These will normally take you right to where the benchmark is located. If the location is scaled it may be off by quite a distance. In either case be sure to follow the description for the benchmark. A TANK will normally be a water tank and as such will vary in size and height. The coordinates will be adjusted, so when you get to the location there should be little doubt about what you are looking for. A SPIRE is normally the "steeple" on a church or a part of the structure that resembles a steeple. Read the description for an accurate description of what the 'Station' is and what part of it was "Intersected".

A few more comments about the missing disk and stem. If the measurements from the track, etc. agree with the description, then I would definitely submit a recovery stating that a drill hole was found at the measured location but the disk and stem were missing. Since the elevation point on a survey disk is the top, center of the disk, once the disk is gone the elevation point is gone. As others have stated, since you don't have the disk in hand, you should not report it has destroyed, just not found, and disk and stem missing from the drill hole found. Again, as others have stated, since elevation points (bench marks) don't have reference marks, you don't have exact measurements to pin point the location of the bench mark. If the mark had been a horizontal point and the stem remained, then the center of the stem could probably be used to recreate the horizontal point, since the center of the stem would be the same horizontally as the center of the disk (just a little bit lower). And, the stem could be checked by measurements from the RM's. I have done this for third-order surveying. Regarding setting up equipment over the bench mark, earlier posts are correct that originally all that was set on the disk was a level rod. More recently however, bench marks are sometimes occupied with GPS to obtain orthometric (NAVD 88) heights for a GPS project. Sometimes setting up a tripod over a bench mark is a challenge. Note, some bench marks are tidal bench marks and have elevations relative to a nearby tide gauge (USC&GS or NOS bench marks). Others have elevations relative to the national network, NAVD 88 (NGS bench marks). (I am using the term "bench mark" to only mean points with accurate elevations.) The specifications NGS uses for photographs of a survey mark in contracted surveying projects are at: http://www.ngs.noaa.gov/ContractingOpportunities/SOWV7.pdf, scroll down to page 165). These specs. include sample photos. Regarding data for survey marks, disks stamped TRIANGULATION STATION (USC&GS), TRAVERSE STATION (USC&GS), or HORIZONTAL CONTROL MARK (NGS) established pre-GPS (~1983) almost always have 2 or more reference marks and have adjusted, accurate horizontal positions. Most of these have approximate elevations determined by using a theodolite to measure vertical angles. These elevation are only approximate and were used in the data processing of the horizontal survey. Occasionally, an NGS leveling crew would include one of the above horizontal points in their vertical survey. In that case the horizontal point would gain an accurate elevation. For disks stamped BENCH MARK (USC&GS) or VERTICAL CONTROL MARK (NGS), they almost always have accurate elevations. Occasionally a horizontal crew might position a bench mark in which case it would gain an accurate position. Note, there are other types of USC&GS and NGS marks out there that have other types of data including some marks with neither horizontal nor vertical data. USC&GS: TOPOGRAPHIC STATION - horizontal position, probably third-order HYDROGRAPHIC STATION - horizontal position, probably third-order (Triangulation stations were mostly first-order or one part in 100,000. Third-order is one part in 10,000.) MAGNETIC STATION - magnetic declination readings GRAVITY STATION - gravity reading NGS: CALIBRATION BASE LINE - Several of these, in line, define very accurately measured distances used to calibration Electronic Distance Measuring Instruments (EDMI). Most CBL disks do not have accurate horizontal or vertical data. GRAVITY CONTROL MARK - as above GEODETIC CONTROL MARK - usually has been occupied with GPS so has good horizontal and vertical data. I have written a paper on all the different USC&GS, NGS, and NOS disks and it is in final editing. A portion of the paper is now on-line at: http://celebrating200years.noaa.gov/survey...ks/welcome.html

Well I suppose the locals might form an instant opinion of a new hider whose first and only contribution to the game was a death-defying challenge for freaky cat-like climbers You could put out a much more straightforward one at the same time if that bothers you.

Part A: 1) Monarch Butterfly 2) Coho Salmon 3) Grey Whale 4) Canada Goose 5) Green sea turtle 6) Arctic Tern 7) North american Caribou Part B LADYBUGS!!! (I love that insect!!!) Ladybugs (also called lady birds or lady beetles) are small, oval-shaped winged insects. These shiny insects are usually red with black spots or black with red spots on the wing covers. The number of spots identifies the type of ladybug. Most ladybugs are less than 1/4 inch (4-8 mm) long. As ladybugs age, the spots fade. There are about 5,000 different species of ladybugs throughout the world. A common species is the two-spotted ladybug (pictured above); it is orange-red with two black spots. The ladybug, like all beetles, undergoes a complete metamorphosis during its life. The life stages of the ladybug are: egg --> larva --> pupa --> adult. These tiny predators (Family Coccinellidae) are helpful in gardens because they eat many garden pests (including mealy bugs and aphids). Birds are the major predator of the ladybug. I heard that there are "farms" now with ladybugs... where you can buy ladybugs to "clean" your infected plants (from the animals that ladybug eats), instead of using chemicals that are bad! I do not know if that is true... but it is surelly a good thinking.... When not flying, the wings are covered by a pair of modified wings (called elytra). When flying, the elytra open up. Like all insects, ladybugs have: 6 jointed legs (black), two antennae (black), and an exoskeleton made of chitin (a material similar to our hair and fingernails). Their three-part body consists of a head (with the mouthparts, eyes, and antennae), thorax (where the legs and wings attach), and the abdomen (containing the reproductive and most of the digestive organs). Ladybugs migrate too! They are mostly in groups and when there is a lack of food and some start to die or a change in the temperature (can not live in low temperatures), their leader takes them in other places! In america ladybugs are migrating to North America in the Summer and in south America in the winter! Four ladybugs were sent into space in 1999 on NASA's space shuttle led by Eileen Collins. Ladybugs and their main food, aphids, were sent to a zero-gravity environment to study how to aphids could get away from the ladybugs without being able to jump using gravity. the greek name of the ladybug is Πασχαλίτσα (paschalitsa). Pascha is Easter!!! Probably that is because of their colour.... red and black... and because they appear when we have Easter... (spring)! It is consider as a good luck if a ladybug lands on you!!! But it is also a bad lack if you throw her away, force her to leave...!!!!

+1 If one magnet can be placed on the back of the aluminum structure, and one inside the container, all you need is some rubber cement or other adhesive to hold the magnet in position. Use an adhesive that can be removed without a lot of trouble, if the cache becomes archived. If the OP is hoping to use "Velcro", test it for a while. There are expensive alternatives to what you find in an office supply store, "Velcro" that might work outdoors. You definitely don't need to be scraping old glue off a sign several times a year. But I like the idea of a secure, defined spot where a container can be easily put back in place. Several of my caches are like that. None of them are found by pulling a container's Velcro apart, since I never got that idea to work. I wrap a branch with Velcro, then the container is held by gravity or with magnets. I often wrap a micro tube in Velcro, because it creates a great surface for epoxy or other adhesive. I also have stuck a little patch of Velcro under a picnic table when the actual container is nearby and not a Velcro hide. Just to be evil.

fyi Marks are never removed from the database, they are only flagged to not show up in a normal search. You can still call up DESTROYED MARKS if you know how. Example I just pulled up...

I think you're interpreting "first to find" too literally here. In your case, an ant could be the FTF, since the phrase isn't restricted to humans. In the context of the geocaching side-game, FTF doesn't always mean "first to find." Instead, it means what the local FTF community more or less agrees it means. As I mentioned, personally I do not care about whichever way someone interprets FTF. In any case I have a good laugh at statements like e.g. the following "Everyone that finds this cache on the first day (it has been the day when an event took place) is FTF". I did not write about claiming FTF, but rather about *being* the first to find. I do not care if 100 people claim ftf - I just have a good laugh if they claim a ftf and are maybe the third to find a cache. It just sounds funny and is defying the logic of the language used. I'm aware of that and do not object. Still it is not the same as being really the first finder. Personally, I feel that the only real challenge of a first finder could be to cope with mistakes, bad coordinates etc - if there has been a beta test, this aspect is missing as is the aspect of finding the cache in its original state. Well, if they prefer to use terms that are saying something else than what is meant, let them go. I still stick with my opinion that it is misuse of terminology as often in geocaching. For example, many German speaking cachers use the phrase "einen Cache mitnehmen" (picking up a cache) even though of course they are not taking away the cache, but leave it at its hideout and do not take the container with them.

The knowledge of local and absolute gravity is a very important function in Geodesy. Determination of accurate heights requires a knowledge of the Earth's gravity field. When a surveyors level their equipment that process is with respect to the local attraction of gravity, which then must be related to our knowledge of the mathematical model for the size and shape of the Earth called the ellipsoid. Look on the NGS web site at: http://www.ngs.noaa.gov/GRD/GRAVITY/ABSG.html, and you will get an idea of some of the work currently being done in this area.

Very similar to all the rest. Here are some links for reading. Gravity GPS Positioning for Helicopter Gravity Surveys BP to do Gravity Surveys at Prudhoe USGS Geology If you type in "Gravity Surveys" in Google, you will find some more links to interesting sites.

Ok, here's a twist for you to put in your Cache Box. Prosser, Washington, GC1JPVS, Gravity Hill Go enjoy yourself at this Cache then let you car drive itself uphill after your find.

Although tree-less campsites are not our first choice, our popup has an awning to create it's own shade and a/c to keep us cool, if necessary. Yes, indeed, Larry Gray's anti-geocaching policy has affected attendance and camping at "his" park, at least in our case. Mrs. Car54 thats the problem, i dont think many are understanding that the CSP doesnt nessecarily have an "anti -geocaching" policy. its just being made out to look that way. look at the facts and its clear to see the geocachers left the CSP rangers no other choice but to remove the caches. and since they have allowed 1 since, id say they very much DO NOT have an anti geocaching policy but yet the local cachers have an anti csp policy. if you werent aware, there is a statewide law now saying that any geocache on state property has to have a permit, and only so many geocaches per so many acres are allowed. so to LEGALLY be able to have a cache placed there, there needs to be a permit applied for and received before the cache is ever placed! and in a park the size CSP was at that time, only about 5 caches would be allowed total. caches without a permit were to be removed. that went into affect jan 1, 2005 and it wasnt just sprung on us, there was speak of it in another thread on here long before jan 1. the policy was well known about now, knowing that. lets look at the cold hard facts on the topic. if you read it thoroughly i think youll see my point. there is talk of upwards of 50!!!!!! caches in this rather smallish park before the law went into affect. am i the only one who thinks this is overdoing it some? geocaching policy sates you shouldnt just place a cache cause you can and 50 in this park is very much a bunch of "just cause i can" caches and overdoing it quite a bit IMHO. Clark state forest, 15 miles away. is 10 times the size od CSP and im willing to bet theres not 50 in its boundaries total, and if so, its not much more than that. the park really was overwhelmed with caches. the law went into effect on january 1, 2005. not a single one of those 50 cache placers applied for a permit for their cache. and probaly a cache or two was placed in the park after this date without applying for a permit first. and none of those 50 caches were removed by the owners like they should have been since they had no permit. many of the caches in this park were placed in a nature preserve or on historicly important grounds. both are no-nos of both geocaching.coms policys as well as the indiana state geocaching policy. this shouldnt have been taking place no matter how wonderful the sites may have been. the park put up with this for 3 months and saw that no one was going to take the new policy seriously. everyone kept ignoring the policy. the policy started on jan 1, and the park rangers didnt start enforcing it until the end of march 2005. over 3 months for geocachers to conform to the new indiana state LAW. everyone ignored it for the most part. the geocachers left the park no choice but to remove all geocaches in the park. for gods sake im a geocacher myself and i can understand this very easily. if i were the park ranger, even being a geocacher myself, i wouldve done the same. in the time since, a couple permits have been applied for. one denied because its in a nature preserve which is a LAW, not park policy. 1 of which was ALLOWED! andthen theres another cache placed in the park thats without a permit but the rangers just cant find it! hows that for defying authority youve gotta play by the rules, or dont play. the cache owners had over 3 months to apply for the permits. if you really wanted yours there, you shouldve been applying for it on dec 31 knowing that there would be limited availability. i think everyone has made it clear no one is interested in playing by the rules. how many caches statewide are on state grounds without permits? my guess is litterly thousands. and thats saying very poorly for geocachers as a whole. its openly showing we dont wanna play by the rules and outright defying the LAW. if you park in a no parking zone you get towed. if you drive with no license you get your car taken away. its only common sense that if you place a geocache without a permit, or in a zone not designated for it, that itd be moved. is this hard to understand? by geocotting the place, the geocachers doing it are making themselves look that much more defiant. very outrightly showing that they dont wanna play by the rules and making a bad showing for geocachers everywhere. i think its very clear charelstown state park doesnt have an anti geocaching policy. and to prove so in the next couple weeks i think ill apply for a permit to place one there thats not in a nature preserve or on sensitive grounds inside the park. well see how it goes

Come Together Geocoin (Two Parts): - 1,75 inches (44,45 mm); 3 mm thickness - Set with two pars (both coin with its own icon) - numbered (sets have the same number) - Set: Antique Silver / Antique Gold 11€ (app 13.80 USD) / set (both trackable with different icon) - Set: Antique Nickel / Antique Copper 11€ (app 13.80 USD) / set (both trackable with different icon) - Set: Foogy Silver / Foggy Gold 11,90€ (app 14.90 USD) / set (both trackable with different icon) Many thanks to fox-and-the-hound for the design support 1905 Albert Einstein (1879-1955) published the „Theory of Special Relativity“: One of many amazing cognitions: Moving clocks lose time. This isn't an effect only referring to clocks, moreover the time itself in a moving system underlies the so called time dilation In our normal (Non-Geocacher day) we do mot recognize this effect since velocities are too small and therefore time differences are not measurable.. 1916 Albert Einstein finished his "Theory of General Relativity": Clocks within a gravity field lose time. A clock on the Moon will therefore measures a longer time than a clock on our Earth, since Earth's gravity is larger. 1950+ Ivan Getting (1912-2003) significantly participated in the basic developments for the GPS. For further explanation of the GPS functionality the interested geocacher surely is aware of 1001 sources in the internet.. 2000 Bill Clinton "turned off" the artificial deterioration of the satellite signal, clearing the way for the civil use of the satellite navigation for us geocachers.. What the hell is the connection between Einstein and Geocaching? There aren't any caches on the Moon, are there? And we do not know geocachers in supersonic aircrafts searching for a cache. Nevertheless without taking into account the above mentioned effects, which partially compensates each other, an adequate precise measuring of the position would be impossible. Neglecting the effect of the moving clock in the satellite and the stronger gravity field for the clock in the receiver on the Earth, even after only one day the position error would have summed up to nearly 12000 meters. Even after a few minutes the search for Tupperware boxes would be a nightmare. Thus, only due to combining the scientific efforts of Einstein and Getting - symbolized by the two parts Yin and Yang - our hobby geocaching is enabled. Therefore: Come Together – Go for the Cache ! Come-Together-Challenge Goal: Both parts of one Come-Together-Pair with same consecutive number (Yin and Yang) have to be placed seperately in distant caches. These coins shall find together within a given time in one cache. Winner is the team, whose coins has reached most points (Point rating see below) at that time the coins have found together. “Not Come Together” coins (those which have not reached the same end location) will not be awarded. Race time will be 3 months. The Winner, 2nd and 3rd will be honoured with a Come Together Coin pair in Gold (1st), Silver (2nd) and Bronce (3rd). Rules: 1. Each team is allowed to start with as many as desired coin pairs. The informations have to be transmitted via a formular provided by the organizer. 2. At the given date x (start) the organizer documents the positions of all coin pairs. 3. Now the race starts. 4. Each half of the coinpair may only be retrieved once by one and the same person. (This shall avoid, that one and the same cacher transports the coins from cache to cache) 5. The owner itself must not retrieve the coin. 6. Logs in virtual caches aren’t allowed. 7. Communication between the owner and the coin retrievers in order to control the travelling are highly appreciated (Come Together!) 8. Those one who retrieved a coin has to be the same who puts the coin into the new cache next time (this shall avoid sending of the coins via mail, except for the start) 9. The Come Together of the coins has to be documented by photo (Photo has to be sent to the organizer) 10. In case of breaching the rules the organizer reserves the right to disqualify the player from the challenge. 11. The documentation is done by the organizer. Point Rating: 1 Point per log in the cache 1 Point per 20 km distance (Distance between the Starting caches) 10 Points for each visited country (each country only one count) Here you can order this Geocoin set: Geocoinshop.de

>I believe that the USGS became part of the NGS which is now part of NOAA, I don't think so. I've not heard that, and they still have separate web presence. http://www.usgs.gov/ http://www.ngs.noaa.gov/ >so USGS marks from the early 20th Century could/should be in the NGS database Even if the agencies were to be combined, the USGS data is in file cabinets and nobody is going to fund the effort to digitize millions of data sheets on marks that are often not as accurate as the NGS data, especially in these days of precision GPS. >I've heard through the grapevine that NOAA no longer cares much about intersection stations, but does still care very much about benchmark disks. That's official, and will be true at least until the planned new vertical datum is released in about a half-dozen years, based on GPS+gravity at any location instead of the older optically leveled data on the existing marks. >older disks were often stamped with their elevation as of when they were set. USGS has done a lot of that. CGS/NGS hasn't done that for a long time, if ever. >However, sea level has changed over the past 100 years Actually, irrelevant here. The older National Geodetic Vertical Datum of 1929 (NGVD29) was based on an average of sea level at several locations. Sea level is hard to measure precisely because of tide patterns that take years to repeat, differences in salinity, currents, etc., so locations will not agree with leveling measurements between them. After gathering much more data they released the North American Vertical Datum of 1988, which is still in use. It was based on picking one station and making all others in the US, Canada, and Mexico relative to that one. No adjustment is made in the vertical datum for sea level changes. The difference between datums can be quite significant but varies from region to region. The difference between datums has caused some people to think it is a measure of sea level change, but it is not.

Did KayakBird answer your question or are you actually looking for the NGS link? Here it is if needed...NGS PID Link Nice CGS+SS disk! I query the NGS site by county as the state search times-out for me. I convert the results to gpx files and then upload them to GSAK. In GSAK in the filter area, I use the Full Text Search box to search by disk type. If I'm looking for a Magnetic Disk I enter MARKER: DM That searchs the datasheets for that match. If you need a list of the 2 letter disk codes let me know. I have an excel sheet with all the Gravity and Magnetic disks in the U.S. If you want it, send me a note. Searching by county is very tedious but effective. If somebody knows a way to search by State, without it timing-out, pls let me know.

Feliz Navidad. I've gone through my files And have found seven of the eleven varieties. #8 Tidal Bench mark was the hardest to locate since it is also designated 'bench mark'. But I have found two of them. And at least three 'and state survey' disks. I also did search for a 'traverse station' disk at the time capsule at the New York World's Fair 1929. But that was destroyed by the new time capsule for the more recent World's Fair. My question is: How do I find listings for the for types that I have not found: topographic, gravity, traverse and magnetic? Hmm... Didn't there used to be a place where I could type in the PID and see the bench mark page on geocaching? Was going to upload some 'and state survey' pictures.
