About this map

Humboldt National Forest encompasses the high, drainage-rich terrain shown here in the early 1980s. The map is defined by the prominent Black Ridge and Mahogany Ridge, which separate various seasonal and perennial water systems. A single identified settlement, Cabin, sits in the northwest near the North Fork Creek, while the rest of the landscape is dominated by ranching and transit infrastructure such as the Bradshaw Road and various jeep trails.

Water management is central to this environment, evidenced by the high density of named water sources like Recanzone Spring, Big Springs, and Cool Pit Spring. The intricate drainage network includes Dutch John Creek and Martin Creek, which cut through deep terrain features like Deep Box Canyon. This survey captures the specialized high-desert geography of Humboldt County, where named springs and canyons served as critical landmarks for navigation and land use.
