2011 Map of Leonia

About this map

The Kootenai River carves through this northern landscape where Idaho and Montana meet, anchoring the small settlement of Leonia. The area is defined by its deep drainages and prominent peaks, including Leonia Knob, Timber Mountain, and Star Mountain. For genealogists and local historians, the Boulder Creek Cemetery stands as a significant landmark near the river's bend. The map illustrates a network of forest roads and namesake routes like Twentymile Leonia Rd and Leonia Rd that navigate the steep terrain. Numerous watercourses such as Boulder Creek, Idamont Creek, and Star Creek feed into the river system, reflecting the hydrologic character of the Cabinet Mountains region. This 2011 survey captures the interface of the river valley and the high-elevation slopes of the National Forest, providing a clear view of the infrastructure and landforms at the turn of the decade.
