2023 Map of Boulter Peak

About this map

East Tintic Mountains dominate this high-desert landscape, where three Utah counties—Tooele, Utah, and Juab—converge near Boulter Peak. The area serves as a significant drainage divide between the northern Rush Valley and the eastern Cedar Valley. This modern survey details a network of canyon access points and historical transit corridors, including Twelvemile Pass, which has long provided a natural break in the terrain for travel between the valleys. The prominence of features like Miners Canyon and Black Rock Canyon suggests a history of resource exploration in these highlands. On the southern slopes, Dry Lake sits as a seasonal catch basin, while numerous canyon roads like Barlow Canyon Rd and Broad Canyon Rd track through the deep relief of Gardison Ridge and County Line Ridge.
