Columbia River waters dominate the eastern edge of this landscape, separating the high plateaus of Kittitas County from Grant County. Along the river's western bank, the small settlement at Scammon Landing and the southern reaches of Ginkgo Petrified Forest State Park provide evidence of early recreational and scientific interest in the region's unique geology. The terrain is deeply incised by a series of drainages, including Quilomene Creek, Whiskey Dick Creek, and Box Canyon, which flow eastward from the high ridges down toward the river.
