About this map

Caribou National Forest and Bridger National Forest dominate this mid-century topographic view of the High Rockies borderland. The terrain is defined by the sharp verticality of the Salt River Range and Wyoming Range, which guide the path of the Bear River as it loops through Idaho and Wyoming. Near the southern edge, the expansive waters of Bear Lake sit between the Bear Lake Plateau and the agricultural valley settlements of St. Charles, Bloomington, and Paris. The Union Pacific rail line and U.S. 30n serve as the primary conduits for commerce and transit, connecting Soda Springs and Montpelier to the broader regional network. To the east, the Green River valley shows early development near the Fontenelle Reservoir, reflecting the post-war era's focus on water management and resource infrastructure.
