The Siskiyou National Forest dominates this section of the Klamath Mountains, where the deep drainage of the Illinois River cuts through the southern portion of the quadrangle. This 2017 survey highlights a landscape defined by isolated peaks and high-elevation clearings, such as Silver Peak and S Bend Mtn. The naming of numerous meadow-like features, including Silver Prairie, Middle Bald Prairie, and Little Bald Mountain Prairie, suggests specific pockets of open terrain within the otherwise dense forest cover.
