Suguta Valley, Kenya: These images provide wide-area and close-up views of Suguta, today a mostly dry valley, se...

The remote location limits field studies, but data indicate that annual precipitation is less than 300 millimeters (12 inches) a year, while evaporation ranges from 3,000 to 4,000 millimeters (120 to 160 inches). And yet, as recently as 8,000 years ago, this arid valley was a vast lake.

Derived from Shuttle Radar Topography Mission (SRTM) data, the white line around the valley in the top image approximates the Lake Suguta shoreline when water levels were at their highest.
