2021 Map of Knoxville

About this map

Knoxville sits at the heart of this landscape along the border of Napa and Yolo counties, a region defined by dramatic ridgelines and secluded drainage basins. The area's complex topography is marked by the Blue Ridge and Little Blue Ridge to the north, creating a natural divide where Davis Creek and Knoxville Cr flow through the valleys. The map reveals a network of remote access routes like Knoxville Rd and the Foley Ridge Track Trl, which connect high-elevation flats such as Martin Flat and Smith Flat. Further south, the curiously named Mysterious Valley and its associated Mysterious Valley Airport suggest a localized pocket of activity amidst the rugged terrain of Buck Mtn and Adams Ridge. This survey provides a modern look at the hydraulic patterns of the Zim Zim Cr and Eticuera Cr watersheds, essential for understanding the hydrology of this interior California range.
