Dayton serves as the primary hub of this eastern Washington landscape, situated at the confluence of several watercourses including the Touchet River and Patit Creek. The town's layout is well-defined, featuring landmarks such as the Dayton and Columbia County Fairgrounds and the Touchet Valley Golf Course. Beyond the municipal borders, the terrain is shaped by a series of geographic "hollows" and gulches, including Whetstone Hollow, Johnson Hollow, and Mustard Hollow, which illustrate how the valley floor and rising slopes have historically influenced settlement and transport. Small outlying points like Baileysburg and Ronan mark the transition from town to more dispersed land use. The presence of the Thorn Lookout Tower on the eastern edge emphasizes the prominence of the surrounding ridges. This survey details the complex network of agricultural and mountain roads, such as Harting Grade and Kendall Skyline Rd, that navigate the ridgelines and water-carved valleys of Columbia County.
