Geologic map of the Lake Mountain quadrangle, Uintah County, Utah

The Lake Mountain quadrangle is about three miles north of the town of Tridell, Uintah County, Utah, along the south flank of the eastern Uinta Mountains and very northern margin of the Uinta Basin. The area is popular for outdoor recreation, including fishing, hunting, four-wheeling, snowmobiling, hiking, and camping, mostly in Ashley National Forest in the northern part of the quadrangle. Private lands include farmlands and homesteads in the central part of the map area. From the Little Water Hills and south, the land is part of the Uinta and Ouray Indian Reservation. Public access to these lands is restricted unless special permission is obtained from the Ute Indian Tribe. The quadrangle is home to a variety of wildlife including elk, mule deer, several species of birds, and the endangered Utah prairie dog, as well as a wide variety of native wildflowers and plants, all of which make it a beautiful place to visit. Two important landmarks within the quadrangle are Dry Fork Canyon, which cuts across the northeast corner of the map area and contains glacial deposits of Smiths Fork age, and Lake Mountain, the quadrangle’s namesake, located southwest of Dry Fork Canyon. The combined geology of the quadrangle makes for a majestic landscape that begins with low-lying hogbacks and broad valleys in the south and transitions to deep glacier-influenced canyons and broad mountain slopes in the north.
