About this map

Adelaide sits at the eastern edge of the Sonoma Range in this modern topographic study of Humboldt County. The terrain is defined by extreme elevation changes, rising from Sonoma Valley and Clear Valley toward the heights of Sonoma Peak at the northwestern corner. The landscape is a network of named canyons and seasonal water sources, where springs like Reinhart Spring, Granite Spring, and Harry Kaul Spring suggest the critical importance of water management in this high-desert environment.

Evidence of ranching and remote land use appears via Rock Creek Ranch Rd, which winds through the northern drainages near Broad Gulch Creek. The map identifies several distinct high-altitude meadows and basins, including George Baine Meadows and Stony Basin, which provide natural points of interest for those tracing land usage patterns in the Great Basin. The intricate system of drainages, from Layson Creek to the East Fork Clear Creek, illustrates the complex hydrology of the range.
