==Geology== Boulder 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>{{citation|title=Geology of the Rocky Mountains and Columbias |author=Gadd, Ben |year=2008}}</ref> thumb|center|350px|East aspect of Boulder Peak seen from Brown Pass
