Alkali Canyon and its associated Alkali Canyon Rd define the western portion of this high-desert landscape in Umatilla County. This 2017 survey reveals an area primarily characterized by deeply incised drainage systems and a grid of rural access routes following the section lines and canyon floors. To the east, Speare Canyon and Mud Spring Canyon cut through the plateau, reflecting the complex hydrology of the region. The map provides clear evidence of agricultural or ranching infrastructure through the naming of family-related routes like Roumagoux Rd and Speare Canyon Rd. These labels offer a connection to the local landholders and the logistical network required to navigate the area's prominent topographical features, such as Spikes Gulch and Slusher Canyon, which vary significantly in elevation across the township boundaries.
