Alpowa Creek and its surrounding canyons define this corner of Asotin County, where the landscape is marked by deep gulches and high, narrow ridges. In the early 21st century, the area remains dominated by its physical geography, with small settlements like Valentine and Alpowa connected by winding routes such as Howell Grade Rd and Valentine Ridge Rd. The map illustrates a drainage system flowing toward the Snake River, characterized by features like South Deadman Creek and Stember Creek. Notable terrain features include Valentine Ridge, Knotgrass Ridge, and Flerchinger Ridge, which separate the various drainages. Smaller landforms like Driscoll Gulch and Megginson Gulch add detail to the complex network of ravines that define this section of the Washington landscape.
