Couple more slight corrections from my notes. I find fewer of these as time goes on......
WY, 9818->9853.
WY, 7875->Jackson BM. Benchmark is on summit but not shown on map.
WY, Mt Chevo->11423
WY, Blackhall Mtn->10980. There is a second benchmark near the 10979 BM that is a foot higher and stamped 10980. Both next to the lookout tower.
CO, 11412->11460.
Also a question, how did Squaw Mtn in CO end up at 11486' again? Despite the spot elevation and the 11480 contour at the tower, I leveled the middle contour higher in 2006(sight line came halfway up lookout). It was just a cheapo hand level so if someone using other equipment found different I wouldn't be too surprised.
other possibility is rock could have been blasted away to make room for the tower, thus lowering the elevation. That has happened before on lookout tower summits such as Wylies in Idaho:
