U.S. Route 93 traverses the north end of the range between Crystal Springs and Caliente. The elevation of the route reaches 6243 feet at Oak Springs Summit pass. Nevada State Route 317 follows Rainbow Canyon south along the northeast margin of the range between Caliente and Elgin.
The range's crest forms part of the Great Basin Divide between the Meadow Watershed and the Dry Lake Watershed, which includes Delamar Dry Lake and the old mining townsite of Delamar.
The Delamar Mountains Wilderness Area covers the southern portion of the range.
GeologyEdit
The range contains Paleozoic sedimentary rocks which were faulted and deformed during the Sevier orogeny. Two periods of silicic volcanism occurred during the Cenozoic producing multiple layers of ash flow tuff. The first occurred during the Oligocene to early Miocene (27 to 18.6 Ma) with sources from the Central Nevada Caldera Complex and Caliente Caldera events. The Kane Springs Wash Caldera in the central part of the Delamar range and extending into the adjacent Meadow Valley Mountains erupted at 14.5 Ma producing the Kane Wash Tuff.
