Scuba Divers Conduct Pupfish Research

Caption

Scuba divers conduct fish research at Devils Hole, an isolated geothermal water-filled limestone cavern in the Nevada desert. The aquifer-fed pool in the Ash Meadows National Wildlife Refuge, a detached unit of Death Valley National Park, is the habitat for the only naturally occurring population of the endangered fish. It is an extreme environment, with water temperatures and dissolved oxygen concentrations near their lethal limits for fish.
