1973 Map of Floating Island

About this map

Silver Island Mountains dominate this orthophotomap, showing the stark contrast between the elevated ridges and the vast, surrounding Mud Flat. At the peak of this range, Cobb Peak stands as a prominent landmark overlooking the salt flats of western Utah. This 1970s record captures the unique intersection of topography and high-speed motorsport history, as seen in the southern portion of the sheet where the International Racetrack Overrun extends onto the flats. Small-scale mining activity is evidenced by scattered prospects along the western slopes, while the isolated landform of Floating Island rises out of the basin to the east. The map provides a detailed view of the natural drainage and erosion patterns through Silver Island Canyon, illustrating the geomorphology of the Great Salt Lake Desert during this era.
