Onalaska stands at the heart of this Lewis County landscape, serving as a hub for the Cowlitz and Chehalis Railway as it winds through the river valleys. The 1950s terrain is defined by the complex drainage system of the North Fork Newaukum River, Middle Fork Newaukum River, and South Fork Newaukum River, which converge toward the west. Settlement is concentrated along these watercourses and the Cascade Highway, featuring small communities like Silver Creek, Salkum, and Cinebar. To the north, the elevation rises toward Windy Knob and the Snoqualmie National Forest, while the southern reaches follow the Cowlitz River near Mayfield. Genealogists will find the Alpha Cem and several unnamed cemeteries, alongside rural markers such as the High Sch in Onalaska and the State Fish Hatchery along the Tilton River.
