Peaks with registers dating back to the 1940s

These circles at el 11100 indicate the Indians were the first peakbaggers here.

An obscure peak in the Sierra Nevada has the only register I've ever seen with a date preceding 1950. And the only reason it's there now is because I took the page down to laminate it. When I returned it in 2019, the whole jar was gone. I left a new jar but the register thieves will be back. You can count on it.
