Great Salt Lake, Bonneville Salt Flats

This 50-mm photograph of the basin-and-range country of Nevada, southern Idaho, and Utah shows the areal extent of Great Salt Lake (1) in 1973 prior to the lake level increase beginning in the late 1970's. Utah Lake (2) is just to the south. The combination railroad-interstate highway bridge across the Great Salt Lake impedes circulation between the northern and southern halves. The result, as in this photograph, is a brine shrimp concentration and a plankton bloom in the north half (the chocolate brown area) of the lake. (SL2-4-301)


Great Salt Lake, May 1985

Great Salt Lake and the great Salt Desert outline the low areas sometimes covered with water. Sunglint highlights gyres in the surface waters of the lake. Compare the surface area covered by the lake with both the earlier Skylab shots and later 1989 and 1990 photographs. (STS51B-35-096)
