1954 Map of Onalaska

About this map

Onalaska serves as a primary hub in this mid-century portrait of Lewis County, where timber-rich lands meet the agricultural flats of Cowlitz Prairie. The landscape is defined by the complex drainage of the North Fork Newaukum River, Middle Fork Newaukum River, and South Fork Newaukum River, which transition from the elevated Snoqualmie National Forest toward the more settled river valleys. The emergence of recreation and infrastructure is evident near Mayfield along the Cowlitz River, featuring a Gaging Sta and a State Fish Hatchery.
