2011 Map of Leonard Creek Slough South

About this map

Black Rock Desert terrain defines this portion of Humboldt County, where the desert floor meets a complex network of ephemeral watercourses. The Quinn River meanders prominently through the center of the sheet, illustrating the drainage patterns of this arid basin. Tributaries such as Leonard Creek and Sentinel Creek descend toward the valley floor, feeding into the wider hydrological system that includes the Jackson Creek Slough. This 2011 survey captures the landscape as it existed before recent shifts in land use, showing the stark, open character of the high desert and the vital importance of these seasonal waterways to the local environment and historical cattle ranching operations in the region.
