The Tallest Peak in MontanaReaching an elevation of 12,799 ft, this peak stands tall among its many contenders. True to its name, Granite Peak is composed largely of Precambrian granitic gneiss, often with alternating mafic and felsic layers. There are also large concentrations of migmatite, and as is seen all along the Beartooths, mafic intrusions are common. Imbedded in the gneiss are inclusions of metamorphosed country rock (P.J. Thompson 2005). As is seen in the image below, Pleistocene-age glacial activity has given this mountain some very dramatic features. A beautiful arête makes up the main ridge of the mountain, and several cirques have been carved in that create more jagged and sharp features.
Granite PeakOther than its namesake, you might be asking yourself why this peak deserves special attention. It may not have any stand-out features in comparison to its neighboring peaks, but Granite Peak tells the story of the Beartooths. It is valuable because it gives you insight on what makes up the majority of these beautiful mountains.
