The Silver Island Range, (also called Silver Island Mountains), is a mountain range in Utah, in the northwest corner of Tooele County and the southwest corner of Box Elder County, about 15 miles (24 km) northeast of Wendover.
The Silver Island Range is a rough triangular area which extends 32 miles (51 km) into Utah from the Utah - Nevada border, with the Pilot Valley Playa to the west and the Great Salt Lake Desert to the east. The wilderness area includes 35,300 acres (14,300 ha) with sloping stream terraces, foothills, canyons, and steep mountains. Elevation starts at 5,200 feet (1,600 m) at the base of the range, to more than 7,000 feet (2,100 m) at the summits. The two tallest peaks in the range are Graham Peak, at 7,563 feet (2,305 m), and Cobb Peak, at 7,021 feet (2,140 m). With no perennial streams, vegetation on the rocky slopes is sparse, consisting of juniper, sagebrush, ricegrass and ephedra along with other desert shrubs and grasses.
Historically, several caves in the Silver Island Range served as habitation for Native Americans. The range also played a role in the more recent mining history of the region, and stood as both a barrier and landmark to pioneers who crossed the inhospitable Salt Lake Desert. Donner Canyon in the northeast section of the range bears the name of the Donner-Reed party, who passed north of the area on the Hastings Cutoff.
