The Amargosa River is an intermittent stream, 185 miles (298 km) long, in southern Nevada and eastern California in the United States. It drains a high desert region northwest of Las Vegas into Death Valley, where it disappears into the ground. Except for a small portion of its route in the Amargosa Canyon in California and a small portion at Beatty, Nevada, the river flows only after a rare rainstorm washes the region.

[edit] Course

Except during flash floods that occur after cloudbursts, most of the course of the Amargosa River is dry on the surface.[5] The flow is generally underground except for stretches near Beatty and near Tecopa, California, in the Amargosa Canyon. In the canyon, the river passes through the Amargosa River Natural Area, a region of dense greenery and prolific wildlife made possible by the presence of water.[6]

The river rises at about 1,200 feet (370 m) above sea level in Nye County, Nevada, along the southern side of Pahute Mesa in the Nellis Air Force Range. Thirsty Canyon Wash enters at the river's source, and when carrying water, the river flows from there southwest into Oasis Valley. Running parallel to U.S. Route 95 near the Bullfrog Hills to the west (right), the river receives Sober-Up Gulch from the right and then Beatty Wash from the left bank. Another 3 miles (4.8 km) or so downstream, the river flows through Beatty, Nevada, and turns south-southeast through the Amargosa Narrows into the Amargosa Desert. At this point, Bare Mountain lies to the left and the Grapevine and Funeral Mountains of the Amargosa Range lie to the right. Downstream of the Narrows, still flowing roughly parallel to Route 95, the river passes Big Dune, which is on the river's left. Shortly thereafter it passes the town of Amargosa Valley on the left, leaves Nevada, and enters Inyo County, California. In this stretch, it receives Forty Mile Wash from the left.[7]

Running roughly parallel to California Route 127, the river passes through Death Valley Junction. Shortly thereafter it receives Carson Slough, which drains Ash Meadows National Wildlife Refuge, from the left. Soon the river passes between the Resting Spring Range to the left and the Greenwater Range to the right before reaching Shoshone. Below Shoshone, the river continues roughly parallel to Route 127 to Tecopa. Downstream of Tecopa, it passes under the Old Spanish Trail Road and through the Amargosa Canyon between the Sperry Hills on the right and the Dumont Hills on the left, enters San Bernardino County, California, and flows by Dumont Dunes in the northern Mojave Desert. Turning west, the river crosses under Route 127 and enters Death Valley National Park between the south end of the Amargosa Range on the right and the Avawatz Mountains on the left.[7]

Turning northwest and then north, the river re-enters Inyo County, passing between the Owlshead Mountains on the left and the Ibex Hills on the right and receives Confidence Wash and Rhodes Wash, both from the right.[7] In this stretch, the river runs roughly parallel to Harry Wade Road and, further north, to California Route 178 and West Side Road.[7] The river receives Willow Creek from the right and ends in Badwater Basin, about 280 feet (85 m) below sea level between the Black Mountains on the right and the Panamint Range on the left.[7] Disappearing into the ground, it feeds the aquifer[8] that is the remnant of prehistoric Lake Manly.[
