About this map

The Great Salt Lake dominates this 1970s orthophotomap, showing the expansive water surface at a recorded elevation of 4200 feet based on 1953 data. Unlike traditional topographic maps, this edition uses an orthophotomosaic base to show the actual texture of the water and shoreline. Along the eastern edge, the steep, rocky terrain of Antelope Island rises sharply from the salt water, providing a clear visual record of the land-water interface during this period. An indefinite boundary marks the aquatic border between Davis County and Tooele County, cutting diagonally across the lake. This survey is particularly notable for its underwater bathymetry, with soundings and underwater contours compiled from data provided by the U.S. Naval Reserve and the Utah Geological and Mineralogical Survey, offering a rare view of the lake bed's profile.
