The Highland Range (Clark County) is a small 10-mile (16 km) long,[2] range south of Henderson, Nevada and connected to the southeast flank of the McCullough Range.

The Highland Range also lies on the southwest border region of the endorheic Eldorado Valley; the Highland Range Crucial Bighorn Habitat Area is a large part of the range's north, and also the alluvial plains on the northeast.

Description

The Highland Range is about 10 miles long.[2] A north section with a ridgeline extends somewhat into Eldorado Valley; the center and southeast gradually lowers in elevation to a mountain pass, and water divide that occurs northeast of Searchlight. The pass and divide is an excursion of the Great Basin Divide around the north, east, and south of Eldorado Valley. A separate pass north of Searchlght carries U.S. Route 95, the route through Eldorado Valley to U.S. Route 93, the road into southwest Las Vegas.

"Searchlight Pass (part of the Highland Range extending into the Newberry Mountains) acts as a barrier between Eldorado and Piute Valleys (Lamb et al., 1989; Hagerty and Tracy 2007). Mountain Pass, which comprises the Ivanpah and Clark mountain ranges, appears to act as a semi-permeable barrier between Shadow Valley and Ivanpah Valley. The New York Mountains isolate Ivanpah Valley from Eldorado Valley. The Spring Mountains and the Spotted and Specter ranges act as a barrier for the western portion of this [Colorado Desert] unit. ... The prominent Providence and New York mountain ranges, which transect Mojave National Preserve, isolate this [Colorado Desert] recovery unit from the recovery units to the northwest. Searchlight Pass is the northern boundary, which separates Eldorado and Piute valleys."
