The Great Salt Lake Desert is a large dry lake in northern Utah between the Great Salt Lake and the Nevada border which is noted for white sand from evaporite Lake Bonneville salt deposits. Several small mountain ranges crisscross through and along the edges of the desert, such as the Cedar Mountains, Lakeside Mountains, Silver Island Mountains, Hogup Mountains, Grassy Mountains, and Newfoundland Mountains. On the western edge of the desert, just across the border with Nevada, stands Pilot Peak in the Pilot Range.
The desert is cool during the winter and includes unusual plants adapted to the dry conditions. Most of the desert receives less than 8 inches (200 mm) of annual precipitation. The salt crust covering the desert reforms each year when the rain evaporates. The military's Utah Test and Training Range is in the northern portion of the desert. The lowest part of Juab County is located just south of the Dugway Proving Grounds, about 1.5 miles (2.4 km) northwest of the northwest corner of the Fish Springs Range.
