2021 Map of Cleghorn Flat

About this map

Madeline Plains and the expansive basin of Cleghorn Flat characterize this high-desert landscape in Lassen County, documented by the USGS in 2021. The map reveals a transition from the broad, open flats of McCoy Flat in the west to the deeply carved drainages of Whiskey Canyon and Chase Canyon in the south. This terrain is marked by an extensive network of water management features, including Bailey Reservoir, Elmers Reservoir, and Steel Post Reservoir, reflecting the importance of water storage in this arid environment. Genealogy interests are anchored by the Dry Valley Cem located near the intersection of several local roads. The road network itself carries a distinct avian theme, featuring names like Canary Rd, Cardinal Rd, and Blue Bird Ln, which suggests a modern layer of naming over a landscape historically defined by its canyons and seasonal creeks like Bailey Cr.
