Siskiyou National Forest land dominates this 2014 survey, highlighting the complex drainage patterns of the Illinois River as it passes through the southwestern corner of the quadrangle. Several high-elevation prairies, including Silver Prairie, Middle Bald Prairie, and Little Bald Mountain Prairie, sit between major peaks such as Silver Peak and Bald Mtn. The landscape is defined by the sharp convergence of multiple watercourses, where Indigo Cr, Silver Cr, and Sulphur Cr carve deep canyons before reaching the river. A notable river feature, Deadman Bar, is visible along the Illinois River, reflecting local landforms within this protected forest. While primary human infrastructure is limited to Nat For Dev Rd 091, the map meticulously documents natural water sources like Polar Spring and smaller tributaries like Falcon Cr and Klondike Cr.
