2011 Map of Blowout Mountain

About this map

Snowshoe Butte Lookout and Big Creek Lookout stand as prominent vantage points across this high-elevation terrain in King County. The landscape is defined by the headwaters of several major drainages, including the Green River, Cabin Creek, and Big Creek, which carve deep valleys between significant peaks like Blowout Mountain and Cabin Mountain. The map details an extensive network of National Forest roads, such as NFD 41 Rd and NFD 5220 Rd, which provide access to remote mountain passes including Sheets Pass, Tacoma Pass, and Green Pass. These routes reflect the mid-twentieth-century development of forest management and fire suppression infrastructure in the Cascades. For researchers and historians, the map's focus on peaks like Bearpaw Butte and Cole Butte offers a clear view of the geographic barriers and transit corridors that have shaped the region's resource-based economy.
