2020 Map of Onalaska

About this map

Onalaska serves as a central hub in this Lewis County landscape, situated near the headwaters of the S Fork Newaukum River and the industrial remnants surrounding Carlisle Lake. The geography here transitions from the wide, open Alpha Prairie in the north to the rolling elevations of Burnt Ridge in the east. Along the southern edge of the survey, the Cowlitz River flows through the fertile lands of Cowlitz Prairie, a region marked by early pioneer settlement and long-standing agricultural use. Local history is anchored by the Alpha Cem and Ethel Greenwood Cem, which provide specific points of interest for genealogical research. The presence of small landing strips like Nelsons Nitch Airport and Burnt Ridge Airstrip underscores the rural, spread-out nature of these communities in the foothills of the Cascades.
