“…The geologic units of the BTNF are igneous, sedimentary, and metamorphic. Granitic and metamorphic rocks are dominant in the Wind River Range, sedimentary rocks are dominant in the ranges of the Kemmerer and Wyoming units, and a mix of volcanic, granitic, and sedimentary rocks form the ranges of the Gros Ventre unit (BTNF 2001(BTNF , 2004Gruell 1980;Wells et al 2015). Mountain ranges of the BTNF originated through various geological processes, with subsequent glacial periods crafting the landforms that currently exist in the landscape (Cooper and Andrus 1994).…”
