2023 Map of Bulls Pass

About this map

North Promontory Mountains rise sharply in this corner of Box Elder County, creating a stark vertical contrast to the drainage basin of Hansel Valley. This arid landscape is defined by the ephemeral Hansel Valley Wash and a network of section-line roads and pass routes that provide access through the high desert. Bulls Pass serves as a critical topographic gap between the peaks, while historical transit corridors like N Hansel Valley Rd and Sunset Pass Rd trace the edges of the mountains. The map illustrates a high-altitude grazing and transit region where the geography is dictated by the availability of water and the accessibility of mountain crossings.
