The Colvin Crew had a nice hike this past weekend to recover this point (12+ miles). This monument was set by NYS in 1904 to perpetuate a V. Colvin monument from 1878 that marked the location of the original 1772 Spruce tree. This point controls almost 5 million acres of land patents in the Adirondack Mountains of NY.

One of Colvin's last points:

and an inscription on a nearby boulder from the surveyor who spun the angles (R D Powers, Apr 27 1898) Sorry for the baby powder, no keel

Very cool! Here is one for you. It is the only international boundary mark WITHIN the U.S. on the line between Texas and Louisiana approximately 150' North of the centerline of Farm-to-Market No. 31 at the state line.

I thought that was pretty cool until I saw it said "Civil Engineering Landmark".

Simple monuments near Tascosa

I don't have any fancy carved monuments from this past weekend. Just a rock mound found by Stan Piper north of Tascosa:

Lots more pictures of the corners we found, but since they are developing a "Locating Original Corners Seminar", I won't be posting them since it would ruin the opportunity for the attendees to find them on their own.

Old fence post stob in ancient fence line:

We had 4 RPLS and 2 SITs doing the field work and base stations on the C&GS tri station and both reference marks. A seismic crew showed up a little after we were setting up and we ended up taking down our base from the station and let them set their rig up. The guyed fiberglassed level rod is their antenna:

We finished with our last point at about 4:30 and decided it was too late in the day to search for another. A line of showers was moving in quickly from the north, so it was a good time to break down anyway.

Nice work, Jim!

I followed the link to your Colvin's Crew site, that's a fantastic thing you guys are doing. I haven't had time to get to everything there, but I will.

Jim,
Thanks for the update on the crews activities. I made the first trip to the great corner back in 1999 on trip # 6. I haven't been receiving any crew updates recently, I'll have to get after Webb to check my email address. The website looks great and I'll try to check it for future trips.
