Wilson Valley and the surrounding drainages of Cache Creek reveal a landscape defined by sharp elevation changes and winding canyons at the intersection of Lake, Colusa, and Yolo counties. This 2022 survey details a region largely shaped by its hydrology and complex topography, where features like The Peninsula and Petrified Canyon suggest a unique geological history. The presence of several distinct flats, including Dunfield Flats and Kennedy Flats, indicates small pockets of level ground amidst the ridges.
