The Promontory Mountains dominate this western Utah landscape, meeting the eastern edge of the Great Salt Lake at a recorded elevation of 4200 feet. The map documents the shifting interface between land and water, where the mountain slopes descend through Maple Canyon and Broadmouth Canyon into the expansive Mud flats of the shoreline. This 1991 revision, based on late-1980s data, illustrates the hydrological environment of Gunnison Bay and Rozel Bay, including several vital water sources along the bench. Local landmarks such as Indian Springs, Rose Spring, and a named Well highlight the locations where water was accessible at the base of the range. Higher elevations are marked by distinctive summits including Mt Tarpey, Rocky Peak, and Messix Peak, offering a clear view of the north-south alignment of this desert range.
