Book excerpt: Excerpt from Range Investigations, Bighorn National Forest, Wyoming, Vol. 1 The Bighorn National Forest is located in north central wyoming, being bounded on the north by the Montana state line (fig. The Forest is entirely within the Big Horn Mountains, although this mountain range extends A0 to 50 miles south and 10 miles north of the Forest boundary. As a result, not more than an estimated two - thirds of the mountain range is within the Forest. South of the Forest, the Big Horn Mountains join the high eastawest range of the Bridger and Owl Creek Mountains. North of the Forest boundary, the Big Horn Mountains end at the canyon of the Big Horn River, north of which the same uplift is continued in the Pryor Mountains, a range of moderate elevation which extends but a short distance (q). In general, the eastern edge of the Forest follows along the face of the mountains, but the western boundary often is above feet on sedimentary formations sloping toward the Big Horn Basin. Underlying the soil mantle and in places outcropping on the surface are both granitic and sedimentary rocks. The granites are extensively exposed in the high mountain areas where the sedimentary layers have been entirely cut away and glacial activity is clearly evident (q). The sedimentary layers consist of sand stone, limestone, shales, and loosely consolidated beds of gravel and sand (iq). The oldest of these sedimentary deposits and the one lying directly on the granite is the Deadwood formation of the Cambrian system. Because of the soft shales in this formation, it has often weathered in long slopes and rounded knobs Bald Mountain is an example (fl). Many of the treeless and brushfree openings or parks on the Medicine Wheel and Tongue Districts (fig. 2) occur on this formation. Sedimentary formations are particularly common on the Tongue, Medicine Wheel, and Paintrock Districts. The other three districts (fig. 1) are characterized for the most part by exposed red and gray granites and soil derived from this parent material. On the Buffalo District, in particular, are found extensive brushfree parks on preglacial deposits of granitic debris (é).
