About this map

Pumpernickel Valley stretches across the northern expanse of this mid-1960s landscape, providing a flat basin that contrasts sharply with the massive rise of Buffalo Mountain to the south. Human presence is sparse but specific, centered around water sources and small-scale operations. Isolated outposts like Ryegrass Ranch and Kemp appear at the edges of the valley floor, while geothermal activity is indicated by Brooks Spring (Hot).

The presence of scattered Mines and a Borrow Pit in the eastern foothills suggests small-scale resource extraction typical of the high desert during this era. Drainage patterns are defined by the seasonal flow of Ragan Creek and the proximity of Sulphur Spring. This survey captures a moment when this section of Humboldt County was defined primarily by its terrain and isolated ranching and mining efforts, accessible by unimproved dirt roads.
