The Piute Valley is a 45-mile (72 km) long north-south valley southeast of Las Vegas, Nevada, and northwest of Needles. The north of the valley is at Searchlight, with some of the valley extending northwest from Searchlight. At the center-north lies Cal-Nev-Ari, Nevada. The second valley southeast of Las Vegas borders to the north, the endorheic Eldorado Valley, with its dry lake. The next watershed north is the Las Vegas Wash Watershed. The northeast portion of the Mojave National Preserve makes up the northwestern region of the Piute Valley, at a four-valley water divide point.
