To know more about this one, you should dig down a little underneath or around that concrete, the rod could still be in place. CallawayMT Quote Link to comment
+Holtie22 Posted April 30, 2007 Share Posted April 30, 2007 Here's what a rod monument looks like in x-section. Berntsen Rod Monument It may or may not have a disk on it. Quote Link to comment
mloser Posted April 30, 2007 Share Posted April 30, 2007 (edited) I agree with CallawayMT. All the 1980s era marks I have found have been stainless steel rods under what is called a "logo cap" and have looked like . I am not sure if concrete is involved in any way--I have never seen any. Just the rod inside the hole under the cap. The piece of concrete, although suspicios, may have been set there to protect or call attention to the mark.

+Black Dog Trackers Posted April 30, 2007 Share Posted April 30, 2007 sweetlife - At this point, this is not a find. It is good to log your picture though, but your log should be a post-a-note or a not-found. I suggest going back with a screwdriver or some other metal thing that you could use to poke into the ground. As the 3 experts before me have indicated, you're looking for a flat thing that is at least 6 or 8 inches in diameter. The existence of something that large and flat is usually findable by some poking around. Pick up the cement block and poke the ground under it (and put it back when you're done). A cement block with a pipe in it is what generally remains when a sign is wrecked or no longer needed. I agree with mloser - the cement is probably just helping the witness post indicate were the marker is. Sometimes a mark is buried under a few inches of sod if the area has changed since 1982. With the mark 1.2 meters below the road, and not very far from it, the area of the mark might be gradually filling in with topsoil. Quote Link to comment
Bill93 Posted April 30, 2007 Share Posted April 30, 2007 See the NGS data sheet. Since the Wisconsin DOT found it in good condition a year and a half ago, unless you see major changes in the area I'd expect it to still be there but maybe under some dirt as others have suggested.

+Klemmer Posted April 30, 2007 Share Posted April 30, 2007 (edited) Did you find the location by using the GPS coordinates, or by following the directions on the benchmark page? This benchmark is "scaled". That means that it could be up to 600 feet off the GPS coordinates. The correct location for this benchmark must normally be found using the directions, not a GPS. You might want to check out the "Me First" topic at the top of the forum, and in particular the "scaled vs adjusted" topic 7. Edited April 30, 2007 by Klemmer & TeddyBearMama Quote Link to comment
