The Bitterroot River valley is the centerpiece of this 1960s survey, showing the development of Hamilton and the surrounding agricultural landscape of the Bitterroot Valley. To the west, the terrain rises sharply into the Bitterroot National Forest, where steep canyons like Blodgett Creek and Mill Creek emerge from the mountains. This area illustrates the critical intersection of water management and western settlement, with the Bitterroot Supply Ditch, Republican Ditch, and Corvallis Canal feeding the valley floor. Small communities such as Woodside and Riverside sit along the valley corridor, while local history is preserved at the Blodgett Cem. Mid-century infrastructure is well-represented, from the Burlington Northern railroad lines to the Hamilton Airport and even a Drive-in Theater near the river, reflecting the region's mid-century growth.
