A view from the St Mary KOA toward Split Mountain (center) and some lenticular clouds.... definitely the theme for the day "lenticular".
Like other mountains in Glacier National Park, Split Mountain 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 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks 3 mi thick, 50 miles wide and 160 miles long over younger rock of the cretaceous period.
