Mount Allen is Peak Six of the Ten Peaks above Moraine Lake, standing high on the Continental Divide near Wenkchemna Pass. In Samuel Allen’s original Stoney Nakoda numbering system it was Shappee, the word for six.

Naming

The mountain was later renamed for Allen himself, the Yale explorer who brought the valley’s peak sequence into published cartographic use in 1894. That makes Mount Allen one of the clearest cases where the older Nakoda numbering and the later commemorative naming history meet in a single summit.

Position in the skyline

From the classic Rockpile view, Mount Allen is one of the central high peaks in the long wall above the lake, though most casual visitors do not identify it by name. It sits between Mount Perren and Mount Tuzo, helping form the high divide at the back of the valley. From Larch Valley, Sentinel Pass, and Wenkchemna Pass, it becomes more legible as an individual summit rather than part of the Moraine wall.

Landscape role

Mount Allen matters less as a famous single peak than as part of the full Wenkchemna composition. The Valley of the Ten Peaks is one of the rare landscapes where the collective name is more powerful than most of the individual ones. Allen’s own legacy reflects that. His name survives on one summit, but his larger gift to the area was the language and structure of the whole valley.
