The Dugway Range is about 13-mi long, with a spur on the south terminus. The spur extends 2.5 mi southwest into the Great Salt Lake Desert. The spur, Dugway Ridge, is about 5-mi long, south-southwest trending mostly, and ends at Pyramid Peak,. The highpoint of the range is Castle Mountain, near the range's center, in the main ridgeline region.
Satellite landforms to the range
With the elevation of the Great Salt Lake about 4200 ft, and Bonneville Salt Flats, at, the surrounding salt flats around the mountain range, are about 4220 ft. Between the Fish Lakes to the southwest, actual foothills above the Great Salt Lake Desert saltflats exist. Washes converge off the southwest flank; they flow southwest, then converge in a shallow valley, with three washes flowing northwest to the GSLD saltflat. Adjacent southwest is a circular, Black Rock Hills,,, 4-mi east of the Fish Lakes, and about 8-mi due southwest of the Dugway foothills. Northeast of the Dugway Range, and east of Granite Mountain are the GSLD salt flats. They extend halfway southeast, along the range's northeast flank, to meet the outflow terminus at the northwest of Dugway Valley, which itself trends mostly southeast, about 17-mi. The valley contains Table Mountain Reservoir, located 3-mi due-west of Table Mountain,. Dissected hills and flats border the valley's northeast; also, with the same northwest trendline as the Dugways, the Old River Bed courses along, about 15-mi, a circuitous wash-bed, containing Old River Bed Road. South of the range at Pony Express Road, is Dugway Pass. The Dugway foothills from here merge south and south-southeast into the northern foothills of the Thomas Range. Adjacent at the south terminus of Granite Mountain, is a small rock "island", Sapphire Mountain,, 1.5 mi long. Sapphire Mountain is 2.5 mi from the Dugway foothills, and 0.5 mi from the Granite Mountain perimeter.
Access
By way of unimproved roads, the Dugway Range can be accessed from the west, the region of the Fish Springs National Wildlife Refuge at the north of the Fish Springs Range; the routes are accessed from Callao, 17-mi west, and about 12-mi from the Dugways. The route from Fish Springs is called Pony Express Road, and transits around the southern range terminus and the Pyramid Peak spur. From Pony Express Road, an unimproved road encircles the mountain range, northwest, north, and east; the route is about 27-mi long. The range can also be accessed from the east, northeast, from Dugway,, on unimproved roads. Dugway is located about 30-mi northeast of the Dugway Range. Off-road routes can reach Granite Mountain from the range's north terminus; Granite Peak "island" is 4-mi distant across the salt flat desert. Other routes from the east, the Dugway region, also access Granite Mountain's east region.
