2014 Map of East Promontory

About this map

The Promontory Mountains dominate this landscape where the high desert meets the northern reaches of the Great Salt Lake. This eastern slope of the peninsula is defined by a series of steep drainages, including Messix Canyon and Chokecherry Canyon, which fall toward the alkaline shoreline. The proximity to the water is most evident at Bear River Bay and the prominent Black Rocky Point. Throughout this arid environment, a network of isolated water sources like Sweetwater Spring, Owen Spring, and Wild Horse Spring historically dictated movement and land use. The presence of Boothe Valley and Miller Canyon further illustrates the complex topographical relief between the mountain peaks and the lake level, providing a detailed view of the remote geography of Box Elder County.
