Sheepy Ridge serves as a stark vertical spine in this mid-1980s study of the California-Oregon borderlands, separating the distinct hydrology of the Lower Klamath National Wildlife Refuge from the sprawling Tule Lake Sump. The settlement of Hatfield sits at the northern edge, where the Southern Pacific tracks parallel the Lost River as it winds across the state line. This landscape is defined by managed water and conservation, evidenced by the extensive grid of canals and dikes serving the Tule Lake National Wildlife Refuge.
