About this map

Cache Creek winds through the heart of this landscape, cutting deep canyons between the prominent elevations of Cortina Ridge and Blue Ridge. The terrain is defined by its dramatic relief, where Glascock Mtn and Langs Peak overlook a complex network of seasonal drainages including Fiske Creek and Bear Creek. This 1958 survey, updated with 1980s aerial data, reveals a wilderness largely defined by its natural topography rather than dense settlement.

Evidence of recreational and early land use is found along the river corridor, particularly within Cache Creek Regional Park and at Camp Haswell. The map identifies numerous springs such as Glascock Spring and Sulphur Spring, which were vital water sources in this dry, uplifted environment. Notable landmarks like Buck Island and the high plains of The Redlands provide distinctive points of reference for those tracing the historical boundaries between Colusa, Lake, and Yolo counties.
