The Stillwater Range is a mountain range located in western Nevada in the United States. It is a SSW-NNE running ridge, approximately 70 miles (110 km) long. It cuts across the center of Churchill County and extends partway into Pershing County.
The Stillwater Range separates the Carson Sink (to the west) from Dixie Valley (to the east). To the north, a low pass separates it from the East Range. To the south, the Sand Springs Pass separates it from the Sand Springs Range. Nestled against the south end of the range is Sand Mountain, an enormous 600-foot (180 m) tall sand dune which draws off-road vehicle enthusiasts from across Nevada and California.
A series of earthquakes measuring 6.6-7.1 on the Richter Scale, centered beneath or near the Stillwater Range, occurred between July and December 1954. As the area was then (and still is) sparsely populated, no fatalities and little property damage resulted. Extensive surface rupturing can be seen on the east slope of the range.
