About this map

The Promontory Mountains terminate at the northern edge of the Great Salt Lake, where the land narrows into the iconic Promontory Point. This map captures the industrial and geographic intersection at Saline, a site defined by the Southern Pacific Causeway as it cuts across the water toward the western shore. To the southeast, the isolated terrain of Fremont Island emerges from the lake, featuring Miller Point and the sheltered Fremont Bight.

The landscape is marked by the sharp contrast between the steep elevation of the mountains and the level expanse of the Fremont Strait. Transport in this remote corridor is limited to the S E Promontory Rd and the prominent rail causeway, reflecting the area's long-standing role as a critical transit point across the salt flats and water. The boundary between Box Elder Co and Weber Co bisects the lake, grounding this topographical study in the political geography of northern Utah.
