Klamath Marsh National Wildlife Refuge dominates the western portion of this 2020 topographic survey, showcasing a complex hydrology of natural watercourses and man-made infrastructure. The Williamson River winds through the wetlands, supplemented by the Kittredge Canal and Williamson River Ditch, indicating a landscape managed for both wildlife conservation and water distribution. To the east, the terrain rises into the timbered reaches of the Winema National Forest, where high ground is marked by the volcanic profile of Wildhorse Ridge and the elongated depression of Skellock Draw. Distinctive local landmarks such as Hog Island, Bloody Point, and Sagebrush Point rise above the marshy lowlands, providing critical orientation points in the vast basin. Isolated water sources like Bluejay Spring and South Fork Spring punctuate the drier forest slopes, reflecting the vital role of groundwater in this high-desert ecosystem.
