Alkali Canyon and its network of dry washes define this section of Umatilla County, illustrating the deeply incised drainage patterns characteristic of the Oregon high desert. The 2020 landscape is marked by a series of significant canyons including Slusher Canyon, Speare Canyon, and the distinct Spikes Gulch. Human presence is traced through a system of rural county roads that follow these natural contours, such as Roumagoux Rd and Mud Springs Cnyn Rd. This survey reflects the modern agricultural and ranching layout of the region, where land use is dictated by the availability of water at features like Mud Spring Canyon. The map provides a precise look at the township and range divisions, showing the intersection of T1N, T2N, and T1S, which continue to govern property boundaries in this rural expanse.
