Why is Death Valley so hot?

Why so Hot? The depth and shape of Death Valley influence its summer temperatures. The valley is a long, narrow basin 282 feet (86 m) below sea level, yet is walled by high, steep mountain ranges. The clear, dry air and sparse plant cover allow sunlight to heat the desert surface.

Swimmers are likely to be coolest some time after exiting the water.”

A water temperature of a seemingly warm 79 degrees (F) can lead to death after prolonged exposure, a water temperature of 50 degrees can lead to death in around an hour, and a water temperature of 32 degrees – like the ocean water on the night the Titanic sank – can lead to death in as few as 15 minutes. Scary stuff.
