Devils Hole is a geologic formation located within the Ash Meadows National Wildlife Refuge, in Nye County, Nevada Southwestern United States.


Devils Hole is a geothermal pool within a limestone cavern in the Amargosa Desert in the Amargosa Valley of Nevada, east over the Amargosa Range and Funeral Mountains from Death Valley. Its waters are a near constant salinity and temperature (92 °F or 33 °C).[1]

Devils Hole branches into deep caverns at least 300 feet (91 m) deep from an opening at the surface that is approximately 6 by 18 feet (1.8 by 5.5 m). According to geologists, the caves were formed over 500,000 years ago.[2] The pool has frequently experienced activity due to far away earthquakes,[1] which have been likened to extremely small scale tsunamis.

Devils Hole is the only natural habitat of the Devils Hole pupfish, which thrives despite the hot, oxygen-poor water. It is an IUCN Red List endangered species. The enclosing cave is occasionally used as a roost for barn owls, which tend to increase diatom growth via guano.
