2020 Map of Riley Butte

About this map

Riley Butte serves as a central landmark in this high-desert region of Washington County, where the landscape is defined by its drainage systems and prominent ridgelines. The map illustrates a network of seasonal and perennial waterways including Milk Cr and N Crane Cr, which carve through the terrain between elevated features like Tennison Ridge and Willow Ridge. Roads such as Riley Butte Rd and N Crane Rd provide the primary access through these upland areas, connecting remote livestock grazing lands and high-plateau spaces like Big Flat. The presence of water sources such as Denton Spring indicates the importance of reliable hydrology in this arid environment, supporting the traditional land use patterns of the Pacific Northwest's interior ranching country.
