About this map

Golden Spike National Historic Site occupies the northwestern corner of this territory, marking the monumental junction of the first transcontinental railroad in the high desert of Box Elder County. The landscape is defined by the sharp transition from the level basins and wetlands fed by Blue Creek to the steep eastern slopes of the Promontory Mountains. Rugged drainages including North Canyon, South Canyon, Davis Canyon, and Big Canyon carve into the range, illustrating the complex topography that early railroad engineers had to navigate. The network of rural routes like N E Promontory Rd and 6400 N Rd tracks the edges of the salt flats and mountain foothills, providing a clear view of the area's modern land management and historical importance to western expansion.
