Chamberlain Mountain and the high peaks of the Garnet Range define this Powell County landscape, which was field checked in 1965. The Blackfoot River cuts across the northern edge of the sheet, fed by a series of drainage systems including Chamberlain Creek, Pearson Creek, and Lobe Creek. These watercourses carve through steep elevation, flowing from prominent summits like Granite Mountain and Green Mountain.
