The Great Salt Lake, the largest inland body of saltwater in the Western Hemisphere, is featured in this northeast-looking, low-oblique photograph. Visible are a railroad causeway separating the two halves of the lake, the white former floor of prehistoric Lake Bonneville spanning more than half of the photograph, scattered clouds, and snow at the higher elevations of the Wasatch Range. The lake’s water level varies seasonally and yearly. This photograph shows water levels higher than normal. Color variation in the lake is caused by higher concentrations of salt in the northern portion.
