Irvine Flats and the eastern edge of the Salish Mountains define this section of Lake County. The landscape is marked by deep drainages such as Garcon Gulch, Black Gulch, and Oliver Gulch, which channel seasonal water toward the lower elevations. The topography rises sharply to Irvine Hill in the west, while the eastern portion of the sheet levels out into the flats. Modern road networks, including Irvine Flats Rd and Spring Ranch Ln, navigate the base of these ridges. This 2014 survey documents the hydrography of Irvine Cr and White Earth Cr as they flow through the township boundaries of T22N and T23N, illustrating the relationship between the elevated mountain terrain and the ranching lands below.
