My Mom shared this bit of news with me a while back.
Here is the mountain south of Fremont Pass/ Climax--Google tells me this is Mt. Arkansas and perhaps Mt. Buckskin:
As folks wandering about were apt to see human and animal forms in the landscape (the Sleeping Ute near Cortez being a fine example), they transformed this into "Sleeping Indian and Horse." (not my artwork)
There are many others along the CC/ DSP&P/ UPD&G/ DL&G/ C&S lines, no doubt. This is one I had not heard before.
