English: The Dumont Dunes Off -Highway Vehicle (OHV) Area, also referred to as an Open Area, is an exciting and remote area for OHV recreation. Bordered by steep volcanic hills and the slow running Amargosa River, the region is easily recognized from a distance by its distinctive sand dunes. Although small in area, the dune system reaches over 400 feet above the surrounding desert floor and contains virtually every type of common active sand dune. Three neighboring sand dune systems are the Valjean Dunes to the east, Little Dumont Dunes to the west and Ibex Dunes located within Death Valley National Park. A favorite location among OHV enthusiasts, the dunes also offer fabulous scenery and opportunities for solitude. The vegetation here consists of creosote scrub, some annual grasses, and wildflowers in the spring. The area is hot and arid, with summer high temperatures ranging from 100 to 120 degrees F. Winter low temperatures may drop below freezing with highs in the 70's. Typical of the desert, winds are frequent and strong, and humidity is generally low. Food, fuel and most necessities are available in Baker, Shoshone, and Pahrump, NV. Cellular phone service is intermittent at Dumont Dunes and is not reliable in all locations.
