1940 Map of Lookout Mtn

About this map

Columbia National Forest dominates this 1940 tactical survey, revealing a landscape defined by fire surveillance and early backcountry infrastructure. The network of peaks, including Siouxon Peak Lookout, Sister Rocks Lookout, and Mowich Butte Lookout, suggests the critical importance of high-altitude observation in this timber-rich region. The presence of the Skyline Road and Telephone Spur Road illustrates the Army Corps of Engineers' efforts to establish communication and transport lines through the drainages of the East Fork Lewis River and the Washougal River.
