Uinta Mountains

Uinta Mountains, segment of the south-central Rocky Mountains, extending eastward for more than 100 miles (160 km) from the Wasatch Range across northeastern Utah and slightly into southwestern Wyoming, U.S. Many of the range’s summits exceed 13,000 feet (4,000 m), including Kings Peak (13,528 feet [4,123 m]), the highest point in Utah. The mountains are a headstream region for the Provo, Bear, and Duchesne rivers and include parts of the Ashley, Wasatch, and Uinta national forests. The Uintah and Ouray Indian Reservation lies to the south.

Great Salt Lake

Great Salt Lake, lake in northern Utah, U.S., the largest inland body of salt water in the Western Hemisphere and one of the most saline inland bodies of water in the world. The lake is fed by the Bear, Weber, and Jordan rivers and has no outlet. The lake has fluctuated greatly in size, depending on the rates of evaporation and the flow of the rivers that feed it. Its surface area has varied from about 2,400 square miles (6,200 square km) at its highest levels in 1873 and the mid-1980s to about 950 square miles (2,460 square km) at its lowest level in 1963. At high level the lake’s surface is 4,212 feet (1,284 meters) above sea level, and at low level it is 4,191 feet (1,277 meters). At times of median water level, the lake is generally less than 15 feet (4.5 meters) deep, with a maximum depth of 35 feet (11 meters).

Map of Lake Bonneville Showing its Extent at the Date of the Provo Shoreline

Map of prehistoric freshwater Lake Bonneville showing its main body and Sevier body, with the Provo water area marked in blue. Lake Bonneville was about 10 times larger than today’s Great Salt Lake which actually is a remnant of Lake Bonneville. The Provo shoreline was formed when the Lake levels stabilized following massive flooding out through Red Rock Pass. Towns and cities throughout the states of Utah and southeastern Idaho are drawn in to show their location on ground once covered by Lake Bonneville. State lines are clearly marked, as well as latitude/longitude. “Lake Bonneville Pl. XIII.” is written at the top right margin. Map was drawn by G. Thompson; printed by Julius Bien & Co. lith. Map colors are blue and black on ivory paper.
