1948 Map of Big Foot Butte

About this map

The Snake River carves a dramatic canyon through this high desert landscape, defining the intersection of Ada, Elmore, and Owyhee counties. Irrigation infrastructure dominates the lowlands at Chattin Flat, where the Low Line Canal, Middle Line Canal, and High Line Canal distribute water across the volcanic soil. This 1940s survey captures a transition in desert navigation, showing the historic Emigrant Trail cutting across the northern plateaus near Big Foot Butte while a modern Landing Strip appears further south.
