1969 Map of Rozel Point SW

About this map

The Great Salt Lake dominates this 1969 survey of the Rozel Point SW area, providing a specialized hydrographic perspective from a time when the lake stood at an elevation of 4193 feet. Unlike typical topographic sheets that focus on landforms and settlements, this particular map is almost entirely composed of open water, utilizing soundings compiled from the U.S. Naval Reserve, the U.S. Corps of Engineers, and the Utah Geological and Mineralogical Survey. This collaborative effort reflects the importance of monitoring the fluctuating water levels and underwater profile of this saline basin during the late 1960s. For researchers and historians, the sheet offers a baseline of the lake's extent and depth before later environmental shifts, capturing a specific moment in Utah's hydrological history through professional survey data.
