True. I typed faster than I was thinking.
I was referring to old USGS surveys in general, whether fence lines, monument corners, geodetic marks, survey markers, etc.

The Colorado/Utah/Wyoming tri-state boundary monument corner is easily 50 yards off of where my GPS says it should be and IIRC the OnX property overlay was off 20-30 yards in the other direction. I do not recall what settings my GPS was on when I realized this though, which may have made difference...

I prefer to just get 2-3 miles into USFS land if possible for the species/tag I have, and only use the GPS to see how far I hiked out of curiosity. It makes things so much simpler.
