2011 Map of Onalaska

About this map

The Middle Fork Newaukum River and South Fork Newaukum River define the northern and central drainage of this Lewis County landscape, centered on the community of Onalaska. A notable industrial legacy is visible at Carlisle Lake, where the Carlisle Lake Dam remains a landmark of the area's timber history. The map captures a transition from the agricultural expanses of Alpha Prairie in the north down to the Cowlitz River in the south. Several small aviation sites, including the Ethel International Airport and Burnt Ridge Airstrip, are dispersed across the territory, reflecting the spread of rural infrastructure. Smaller settlements like Ethel, Salkum, and Lacamas line the east-west transit corridor, while family-named landmarks like the Alpha Cemetery and Powell Dam offer specific points of interest for local history researchers.
