1968 Map of Carrington Island

About this map

Great Salt Lake dominates the horizon of this 1968 orthophotomosaic, which records a specific hydrologic moment when the water reached an elevation of 4,193 feet. The resulting landscape reveals a stark interface between the brine and the surrounding Mud Flat, where shifting shorelines frequently alter the visible geography. Centered on the prominent landmass of Carrington Island, the map details the terrain leading toward Lambournes Rock and includes the smaller outcrops of Hat Island and Bird Island to the north. An indefinite boundary marks the divide between Box Elder and Tooele counties, cutting across the flats where the transition from solid ground to lakebed is often obscured by seasonal water levels.
