Sex Peak – and you can rent the fire tower on top from the Forest Service! Evocative, to say the least.
According to the Forest Service site, “The peak was named by I.V. Anderson, an early forester, and Harry Baker, supervisor of what was then Cabinet National Forest. It is rumored that they named the peak after their topic of conversation at the time.”
