Great Salt Lake and Utah Lake in Western USA40.2N 111.7W
Visible in this image are two lakes in Utah, USA: the Great Salt Lake (above) and Utah Lake (below). The linearly split grey and dark green bicoloring of the former is due to a causeway that runs across the lake and restricts the mixing of the waters between the northern and southern halves. Utah Lake, on the other hand, appears uniformly bright green, probably due to sediments and phytoplankton growth. Unlike its neighbor to the north, it is a freshwater lake.
