71. “Keyhole Plateau”

Officially passes though saddle depth might be less than 300'


Unfortunately, Google Maps decided to discontinue support for v2 of their API, which has resulted in the peak markers disappearing from my topographic maps. I'm working on a solution now and hope to have this fixed within a few weeks.
