The
Lahontan Valley is in
Churchill County in the U.S. state of
Nevada. 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, and
Humboldt Lake is to the valley's northeast (
Pyramid Lake is west and
Walker Lake is south). Aside from the city of
Fallon, the railroad junction at
Hazen, and the ghost town of
Stillwater, the Lahontan Valley is mostly uninhabited desert. During the era of the
California trail the Lahontan and adjacent valleys to the northwest were called the
Forty Mile Desert.
