2023 Map of Jackson Prairie

About this map

Jackson Prairie defines this landscape south of Napavine, where the lowlands of Lewis County are shaped by a complex network of waterways. The Newaukum River and its multiple forks—the North Fork, Middle Fork, and South Fork—meander through the northern half of the map, while the southern reaches are drained by Lacamas Creek and Mill Creek. This geography created fertile ground for several distinct prairie settlements, including Newaukum Prairie, Lacamas Prairie, and Cowlitz Prairie. At the central junction of the Jackson Highway and State Route 12 lies Marys Corner, a key waypoint for travelers. Local aviation history is represented by small airfields such as Dwight Field, Harris Airport, and the Fantasy Field Airstrip. For those tracing historical routes, the Lewis and Clark Trail corridor passes through these open prairie lands, reflecting the enduring importance of this north-south transit passage.
