The Great Salt Lake, located in the northern part of Utah, is the largest salt water lake in the Western Hemisphere, and the fourth-largest terminal lake in the world. In an average year the lake covers an area of around 5,100 km², but the lake's size fluctuates substantially due to its shallowness. The lake's salinity fluctuates between 5 and 27%, being higher than that of seawater. On this 100 m image of 10 October 2014, the lake is visible to the right, with Lake Utah to the south. South-west of the Great Salt Lake, the white salt of the Salt Lake Desert is visible.
