About this map

The Promontory Mountains dominate this landscape where the high desert terrain meets the northeastern shores of the Great Salt Lake. This map captures the transition from the steep, canyon-riven slopes of the range down to the marshes and mudflats of Bear River Bay. Notable topographic features include the rugged Messix Canyon, Chokecherry Canyon, and Broadmouth Canyon, which carve through the mountains to the west.

Hydrological data reveals a network of vital water sources in this arid environment, such as Sweetwater Spring, Wild Horse Spring, and Willow Springs. The peninsula's eastern edge is defined by landmarks like Black Rocky Point and the East Promontory rise. Apart from S E Promontory Rd, the area remains largely undeveloped, illustrating the characteristic isolation of the Great Basin's mountain-and-basin geography.
