2020 Map of Thornton

About this map

Thornton and Sunset anchor this high-relief portion of Whitman County, where the agricultural landscape is deeply etched by winding drainages and a dense network of country roads. The terrain is defined by the branched valleys of Cottonwood Cr and Thorn Cr, while the named settlement of Cashup sits along the eastern corridor. The map reveals a transition in land use and transport, following routes like the Old Thornton Hwy and Cashup Flat Rd that trace the contours of the Palouse hills. Significant local landmarks such as Hastings Gulch and the drainage of Pleasant Valley Cr near Pleasant Valley illustrate the complex hydrography of the region. This 2020 survey provides a precise modern look at the rural township boundaries, including the intersection of t18n r43e and its neighbors, documenting the persistent settlement patterns of this farming country.
