'''Crypt Peak''' is an {{convert|8579|ft|m|0|adj=on}} mountain summit located in Glacier National Park, in Glacier County of the U.S. state of Montana. It is situated along the Canada–United States border, above Crypt Lake, and is partially within Waterton Lakes National Park. Crypt Peak is part of the Lewis Range, and is approximately three miles east of Waterton Lake. Topographic relief is significant as Crypt Peak rises over {{convert|2,100|ft|m|abbr=off|sp=us}} above Crypt Lake in approximately one-half mile (1.6&nbsp;km), and {{convert|4400|ft|m|-1|abbr=on}} above Waterton Lake in {{convert|3|mi|km|spell=in}}. Precipitation runoff from the mountain drains west to Waterton Lake, and east to Belly River. This geographical feature's name has not yet been officially adopted by the United States Board on Geographic Names.

==Climate== Based on the Köppen climate classification, Crypt Peak is located in an alpine subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers.<ref name=Peel>{{cite journal | author = Peel, M.

==Geology== Like the mountains in Glacier National Park, Crypt Peak is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170&nbsp;million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks {{convert|3|mi|km|1|abbr=on}} thick, {{convert|50|mi|km}} wide and {{convert|160|mi|km}} long over younger rock of the cretaceous period.<ref name=gadd>{{cite book|title=Geology of the Rocky Mountains and Columbias|author=Gadd, Ben |year=2008}}</ref> The reddish rock at the top of Crypt Peak is argillite.<ref>Andrew W.
