1967 Map of East Promontory

About this map

The Promontory Mountains define the western landscape of this mid-century survey, sloping down toward the extensive wetlands of the Bear River Migratory Bird Refuge. Water sources are vital features in this arid environment, evidenced by the numerous named points such as Sweetwater Spring, Wild Horse Spring, and Parsons Spring that dot the mountain flanks. The small settlement of East Promontory serves as a lone human outpost on the higher ground above the expansive Mud Flat and Bear River Bay.
