The Lahontan Valley is a basin in Churchill County, Nevada, United States. The valley is a landform of the central portion of the prehistoric Lake Lahontan's lakebed of 20,000-9,000 years ago. The valley and the adjacent Carson Sink represent a small portion of the lake bed. Humboldt Lake is to the valley's northeast. Pyramid Lake is west. Walker Lake is to the south. The valley is part of the larger Great Basin Desert, however during the California Gold Rush was valley often called the Forty Mile Desert.
Forty Mile Desert
The Forty Mile Desert is a California Gold Rush name for Nevada's Lahontan Valley and the adjoining area to the northwest. Emigrants following the California Trail west came into the Lahonton Valley via the Humboldt River. West of the river's end in the Humboldt Sink, the trail forked, with one branch leading towards the Carson River and the other towards the Truckee River. Regardless of which route they took, the travelers would have to endure about 40 miles (64 km) of desert without usable water. The Truckee route traversed the area starting at modern Lovelock, reaching the waters of the Truckee River near modern Wadsworth. This path is along a series of smaller valleys separated from the main part of the Lahontan Valley by the Hot Springs Mountains. Modern Interstate 80 closely approximates this path. The Carson route across the Lahontan Valley proceeds south from modern Lovelock towards an area west of modern Fallon called Ragtown, which had the last usable water on the Carson River. The First Transcontinental Railroad (modern Overland Route) and U.S. Route 95 loosely follow the Carson route.
Per a state historical marker at a rest area at the junction of I-80 and US 95, the Forty Mile Desert was the most dreaded part of the California Trail. If possible, it was crossed at night. An 1850 survey counted 953 graves along this portion of the trail, along with thousands of animal skeletons and abandoned belongings of the desperate travelers.
