The Umatilla River valley defines the central landscape of this Umatilla County survey, serving as the primary corridor for settlement and transit near Cayuse. The terrain transitions from the high, dissected plateaus of Kanine Ridge and Doe Canyon in the south to the more open drainage basins of Wildhorse Cr and Greasewood Cr in the north. This geography dictates the placement of rural infrastructure, with roads like Cayuse Rd and River Rd following the natural breaks in the topography.
