Great Salt Lake and Desert, Utah, USA - March 10th, 2009

The Great Salt Lake Desert is a large, arid region extending west from the Great Salt Lake in Utah, to the Nevada border. It covers an area of 4,000 square miles (10,360 kmĀ²).

The sand there is white due to the high concentration of salt in the soil. The salt comes mainly from evaporite deposits left by the extinct Lake Bonneville, of which only the Great Salt Lake and Utah Lake remain.

The desert is hot during the summer and cool during the winter. Most of it receives less than 8 in (20 cm) of precipitation annually.

Part of the Great Salt Lake, which appears bright green, is visible at the upper left. This color is caused by a phytoplankton community, dominated by blue-green or green algae, which tints the water in the southern part of the lake.
