While you probably never heard of Shinn Peaks referred to as the Three Sisters, the men stationed at the Secret Valley CCC camp gave it that name. After all these young men, were from the Midwest, so all the region was foreign to them, and Secret Valley so remote where there was not even a small village or outpost to glean local knowledge. Their view of Shinn Peaks shows three distinct peaks, hence the Three Sisters. Of course, some of the men were so intrigued by the mountain that they climbed to the top.
Another landmark Turtle Mountain, at the lower end of the Honey Lake Valley, which is a prominent extension to Fort Sage Mountain never had a name attached to it for many years. According to Philip Hall (1909-1996), who spent most of his life in nearby Long Valley stated it was “new comers” who arrived when the Sierra Army Depot at Herlong that was established in the early 1940s, when the point was named.
