What is at the bottom of Devils Hole?

Devils Hole itself is a water-filled cavern cut into the side of a hill. The cavern is over 500 feet (152 m) deep and the bottom has never been mapped. Devils Hole provides its resident pupfish with conditions of constant temperature (92°F, 33°C) and salinity, unlike the fluctuating environments of many other pupfish.

Winter daytime temperatures are mild in the low elevations, with cool nights that only occasionally reach freezing. Higher elevations are cooler than the low valley. Temperatures drop 3 to 5°F (2 to 3°C) with every thousand vertical feet gained(approx. 300m).

Avoid hiking in the heat: Do not hike in the low elevations when temperatures are hot. The mountains are cooler in summer, but can have snow and ice in winter. Travel prepared to survive: Stay on paved roads in summer. If your car breaks down, stay with it until help comes.
