2018 Map of Denio Summit

About this map

Denio Summit serves as the high point of this high-desert landscape in northern Humboldt County, where drainage networks like Virgin Cr and Sage Hen Cr carve through the high plateaus. The map documents a sparsely populated ranching and grazing environment defined by isolated water sources such as Reese Spring and Houghland Spring. Near the southern portion of the quadrangle, Harden Lake and the nearby Howard Cem provide specific points of interest for local history and genealogical research. The topography is dominated by significant elevations including Granite Mtn and Black Butte, which overlook the deep corridor of Alta Canyon. This 2018 survey detail provides a clear view of the water-dependent geography of the region, tracing numerous seasonal creeks like Shyster Cr and Rattlesnake Cr that feed into the larger basin.
