(DESCRIPTION)
A satellite view of Death Valley, California, USA, shows a colorful arid landscape with hues of green, purple, red, blue, brown, and tan. There is a bright blue section in the center.
 
Text, Death Valley is one of the hottest, driest places on Earth. Summer temperatures rise to well over 100 degrees Fahrenheit but fall dramatically at night.
 
Death Valley is 282 feet below sea level and only receives about 2 inches of rain each year, yet more than a thousand different species call Death Valley home.
 
This false-color image was made using visible and infrared data captured by the Landsat 7 satellite.
 
Green indicates vegetation, which increases with altitude and highlights the juniper and pine forests on the mountain peaks.
 
Dots of brilliant green are likely from irrigation. There are squares of brilliant green gridded out in dry washes.
 
Text, Varying shades of brown, beige, and rust indicate the different mineral content in bare rock and soil.
 
Bright blue-green patches are salt deposits that still hold a little moisture.
 
Fades to black.
