  1. Now if we could just post a recovery? Anyone else having problems?

    The adjustment mentioned is to NAD83 (North American Datum 1983) datum, which was a change to use a different ellipsoid, GRS80, (essentially, the earth's shape) based on the central reference point being the center of the earth, and not the Clarke base station at Meade's Ranch in Kansas. The shift of datum resulted in a grid shift that varied depending on the location in the US and the shape of the ellipsoid used at that location. For a bit more information on the grid systems can be found at http://www.towermaps.com/nad.htm. There is no magic about this site--it is just the first one I came up with on a Google search.
  3. I hope they didn't find the jug! It is under the monument, approximately three feet underground, by the description.
  4. Except for this statement from 1932: A NEW STATION, CAFFEE 2, WAS CAST DIRECTLY OVER THIS STATION, WITH THE STANDARD DISK CENTERED OVER THE ORIGINAL SCREW PILE. SEE DESCRIPTION OF CAFFEE 2. Which leads me to believe the bottle was either removed or cast into the concrete monument. Many of these older stations were replaced by standard disks, often in the 1930s it seems, in order to ensure their permanance.
  5. I have traveled to Seattle, Boston, Connecticut, and Florida to hunt benchmarks... Ok, I lie, I did find benchmarks there but the trips were for other reasons. I just can't go anywhere without getting an out of area mark though! The furthest I have traveled JUST to get a mark is about an hour. It was an 1885 mark that hadn't been recovered since and was a granite block on a mountain. The reason I haven't traveled too far is that there are so many close ones to get. As I pick them up I have to travel more and more. The closest marks I haven't found (excluding my list of "trouble" marks that I keep going back to again and again, hoping something changes and I can find them) is about 30 minutes now and moving up quickly to 45.

  6. Me & Bucky, I totally concur! The chiseled squares are great, because you know someone worked to get that mark there--stood or sat on that spot, maybe over 100 years ago, and left what he hoped would be used by future generations. I have yet to find any evidence of an airway beacon (just looked for one today, with a total lack of success, see KW3089), but I know of at least one remaining foundation within easy reach that I will get to. A second aspect that I didn't mention is the people you meet. Although most requests to venture onto someone's property are handled with a quick "yes", there have been some interesting ones in my hunts, including people who remembered the marks being set, and one man who remembered climbing the Bilby tower with a friend as a kid. He overestimated the height of the tower by a factor of two (based on the height of light) but I wasn't about to contradict him while he gave his first hand account. He was also the one who showed us where the destroyed reference mark was located, about 100 feet away from its original location. He was pretty coy in not mentioning how that mark GOT there. Others have told me local history, or have just been friendly or amusing. Some have helped me dig in their yard, out of curiousity to find the mark or perhaps to see what the nutcase with the camera and tape measure was looking for. A hunt for one triangulation station ended, successfully, after talking to 5 different people. Yep, I have gotten some funny looks, but NEVER, ever a turn away! Finally, with due respect to some here who don't see this the same way I do, I get a large charge out of reporting my finds to the NGS, and knowing that what I did will be available for surveyors to use as a help in locating stations. It just feels good to help others, and to have fun doing it! Matt
  7. I agree PFF. GNBrotz and I did a team hunt in late summer 2004 and were able to cover a lot of territory, searching for about 20 marks. It also helps to have someone to discuss the descriptions with--which tree is an oak, was the road always this wide, etc. And to have two people on the tape measure is heaven! He and I will probably get together this spring or summer for another hunt. One thing I have to admit, as that although I enjoy shared hunts, I also enjoy being alone and doing hunting all by myself. Both are great ways to spend a day or afternoon.
  8. Yes! What an achievement! I can only hope for 2,000 by the time I die, if I live a long time too! That said, it might be time for a check on stats again. We did this a little less than a year ago, and might want to do it periodically, unless Jeremy wants to provide a way for us to list the benchmarks by number of finds (hint). I stand, as of this afternoon, at 412 found. Yesterday marks my 1 year benchmarking anniversary, and I was hoping to find 500, but with the year I just had, I am happy with what I have. Matt
  9. Actually, the NGS criteria for marking a tower as destroyed are not as strict as with monumented marks. You could probably show pictures of the tower with your GPSr in the pic showing the location and Deb would report the old tower as destroyed. I have done this in two cases, one with a water tower that simply no longer existed, and another with a TV antenna on a building that no longer existed.
  10. I am going to get into the "reporting to NGS" fray and say that, although every mark need not be reported, you should consider any with a change in description, no matter how minor. I also report any recovered in about the last 5 years. Just having the fairly recent recovery date, even if it is just as a "found" should be reassuring to a surveyor that the mark stands a good chance of existing. I have searched for and not found too many marks with recovery dates are recent as 10 years, or less, so just the note that the mark was found in the last couple of years may mean the difference between looking for it and not to a surveyor. Try to think of it from a surveyor's point of view--when looking at NGS sheets and there is one that says the mark was set in 1969 but never recovered, yet there is one nearby that was recovered multiple times in the same period. Which would YOU be more confident of finding?
  11. Dave, To follow up on your question about etiquette, I tend to follow Paul's (PFF) quidelines. If I find something different than a previous benchmarker posted I will post my findings, no matter what theirs were. Just like Paul I have had a difference of opinion about some mark, and have stated simply what I found or did not find. I almost always check the statistics of the user to see if they are what I would consider a "serious" benchmarker. If they are I will sometimes email them with my find status, as a courtesy and to see if they might have found something I didn't find, or didn't find something I did find. I would appreciate the same courtesy if another hunter discovered a discrepancy in one of my finds. Matt
  12. Thanks! That actually helped a lot, not so much knowing that there were "rules" because there had to be rules, but how you guys thought it out and approached it logically. To (hopefully) continue this discussion, a couple further questions: How long did you spend on a mark? For example, if you were setting a mark by the road in a concrete monument, how long did you spend at that location, in setting and surveying the mark? Can you break down the process for us and how you went about it? I assume you had to ask permission to set a mark on private land. Was it ever denied? What was your backup plan in that case? I could go on (and on and on) but will let you off with just these few right now. Thanks for your earlier response! Matt
  13. I am willing to bet Superpowerdave found the markers but just didn't know it. The other poster hasn't posted a pic of anything yet, and his posts are a bit vague, so it is hard to tell what he located. Also, nobody spotted the marker that is actually a disk, right by the main entrance door. Is it still there?
  14. In the original NGS datasheet no marker type is listed at all, despite what is says on the listing on the Geocaching site. That usually leads me to believe I can be looking for just about anything, but a disk is not among them. Without pictures of the finds from the other benchmarker, nobody can be sure if what HE found was the mark or not. I suspect that if you found two metal rods on the window sills in question, and there weren't similar metal rods on other windowsills, you may have found your marks. It could help to do the measurements to the mark location also. Also, try to pick up TT0721, which IS a benchmark disk near the entrance to the building and appears to be vertically mounted at the door. There is a measurement from THAT disk to one of the marks in question, which would be very helpful, especially when taking the other measurements into account. In short, I think you may have found them, but more research might help. Can you post pics? You can add them to your recovery and link to them here. Matt
  15. I like when the witness post is still there! Makes you wonder if they even bothered to drive by. I counted on this one: KW1319 being a hard one but with the witness post there it was hard to miss, even in the twilight (I had to use the flash to even get pictures).
  16. From aerial photographs it looks like it will be difficult to get to. I doubt you will have a view of the mark from anywhere but right on the bridge itself. I don't see anything that looks like a walkway near the tracks, unless the walkway is actually ON the bridge, which seems unlikely, as this appears to be a major line for the BNSF at this location. Your best bet, and one you will hear from others on this forum, is to skip this benchmark. It is bad enough to be on railroad property, but being on a BRIDGE on railroad property is about as dangerous as it can get.
  17. Well stated Holograph! Here are some reasons for the new forum: 1) The NGS asked for it! For those of us concerned about reporting our finds to the NGS this is a large step. Ignore that in the past the NGS participation has been spotty. And quit asking them to prove how wonderful the NGS forum would be. Accept their offer at face value and move forward. We won't know what the forum will be like until it exists. 2) There has been more than a little contention in this forum over perceived pressure to report finds to the NGS. Separating the forums would lessen that and allow those of us who view benchmarking as more than a personal hobby to learn more and exchange information about benchmarks. I for one have been nervous about posting anything related to NGS recovery for fear of the inevitable response saying it is just a hobby and not to pressure. Imagine if I asked a more specific NGS-related question?! 3) A pinned question at the top of a forum is not enough to entertain serious discussion about anything. It is pinned so that it can be found quickly, not so it can be used as a discussion board. If we all started to ask NGS questions on the pinned thread it would run to page after page of unrelated questions and answers, all intermixed and all under the title of the pinned thread. Therefore it would become unreadable and unusable. A separate forum would have threads with titles that relate to the topic under discussion. Interested readers could open a thread, uninterested ones could bypass it. Just like I am sure many of us do with threads on this forum. Matt
  18. Thanks Casey. There are quite a few people here who have passed the 400 mark though!
  19. I too was unsure what value the forum would have, but if the NGS is willing to get involved significantly I vote a strong yes!
  20. Unless there is something left of the train terminal that mark is probably gone. You shouldn't need a GPS to find the location. If you click on Nearest Benchmarks on the benchmark site you will get a list of the ones closest to the current one. There are 18 within a half mile radius of DG0217.
  21. Excellent! Keep up the good work. I was looking at marks near you and downtown Atlanta seems full of benchmarks. There are quite a few more in walking distance--not all are under cover either! Also, don't be afraid of the ones that were previously "not found". People make mistakes and all of us here have recovered previously not found marks, some of which were in plain view! Good work!
  22. I have the clipboard. Guess I have some shopping to do for the other stuff though! Actually, I think the minimum thing you would need is the NGS recovery sheet and a pen. Read it, open the cover, make a couple of marks on it, and go. There, you just did something "official". And, oh yeah, don't forget to scratch a bit too (men only).
  23. Very good thought. I have done the same in the early evening in summer, when nobody is around. See: KW0934
  24. Well, it is a hobby and this site is informal, so if you feel you have found them feel free to log them. Me? I would open the covers and verify that the marks were there. Matt
  25. Rob, Yeah, not getting shot is pretty high on my list. I will grab that mark in the spring. There is something odd about the two stations BOYD and NEAR BOYD on that hill that I want to check out. They have been variously "found" and "not found" by benchmarkers here on this site, but I think there is at least one more mark up there that remains to be located if I read the descriptions right. As for safety, you didn't mention, but probably noticed, that most of the other marks I found were along the railroad. There are a number of people here who feel it is unwise to trespass on railroad property, and they are right. However, I take that calculated risk at times, and this was one of those times. The tracks in question are not used heavily--I think there might be one or two trains a day, and since it was a Sunday there was little or no chance of a train. Also reduced on Sundays is the possibilty of railroad police. My caveat: To anybody thinking about doing the same I give the warning to be safe, and be prepared to get caught. It was really the industrial archeology that caught me during my hunt. To stand on the edge of a perfectly perserved canal lock, walk in the ruins of a tenament from an iron forge, and stand in front of an old lime kiln. Wow! What can I say?! To anyone South Central Pennsylvania, the iron foundry is on a walking trail at the base of Chickies Rock. The ruins are about 1/2 mile in from the head of the trail, along an old railroad grade and are an easy walk. If you want more information contact me. Matt
