A large mountain at the SE end of the Fairholme Range directly N of the Bow River. The mountain contains the Rat's Nest Cave as well as many others but most are inaccessible.
The mountain is blighted by a large mining scar running up its SW slopes.
Name Notes: Named in 1858 by Eugene Bourgeau in 1858 after the large cave with a high arched roof which Bourgeau and James Hector found after hiking up a creek on the SW side of the mountain. ""Hector wrote that they entered the grotto and, following a stream, scrambled up 300 vertical feet to a point where they found, "a trickling fall several hundred feet in height, splashing in a clear pool with green mossy bank."" It was here that they performed their "morning ablutions."
