2020 Map of Violet Prairie

About this map

The Violet Prairie and Grand Mound Prairie dominate the landscape north of Centralia, showcasing the glacial outwash plains that define this portion of the Thurston and Lewis County border. The map documents a corridor of transit and settlement anchored by the Skookumchuck River and the historical path of Old Highway 99. Small airfields such as Sorrell Airport and Wissler's Airport serve the rural communities between the more established centers of Tenino and Bucoda. Further south, the landscape shifts toward the industrial and agricultural valley floors of Zenker Valley and Hanaford Valley, where Hanaford Cr and Coffee Cr drain toward the urban fringe. The map provides clear evidence of the area's transition from open prairie to structured residential and agricultural parcels, particularly around the settlement of Sunnydale.
