Schrag and the surrounding plateau of Adams County are defined by a series of glacial drainage features, most notably the winding path of Bauer Coulee. This landscape illustrates the characteristic geology of the Channeled Scablands, where ancient floods carved deep depressions into the basalt. In the early 21st century, the area remains dominated by large-scale agricultural parcels and a geometric grid of rural roads, including W Schrag Rd and Koch Rd, which intersect with the major regional thoroughfare crossing the northern half of the territory. The map provides a precise look at the township and range system, showing how section lines and property boundaries have been superimposed over the irregular natural topography of the coulee systems.
