2015 Map of Duffer Peak

About this map

Duffer Peak and the high elevations of the Pine Forest Range define this high-altitude landscape in Humboldt County. This 2015 digital survey illustrates a complex network of alpine basins and meadows that collect the snowmelt feeding into the surrounding desert. Notable features include Leonard Creek Basin and the Leonard Creek Meadows, while several named reservoirs and natural lakes like Onion Valley Reservoir and Blue Lake sit tucked within the mountain folds. These water sources were vital for the seasonal livestock grazing indicated by labels such as Corral Meadow and Alder Creek Meadow. The map provides a precise look at the hydrology of the range, tracing headwaters for Big Cr, Leonard Cr, and Willow Cr as they descend through rugged gaps like Bare Pass.
