1983 Map of Sonoma Canyon

About this map

The high peaks and drainages of the Sonoma Range dominate this 1983 survey of the borderlands between Humboldt and Pershing counties. The landscape is defined by its verticality, where deep cuts like Mullen Canyon and Sonoma Canyon descend toward the broad flats of Grass Valley to the west. This rugged terrain was a focus for mineral exploration, evidenced by the presence of the Midway Group Mine tucked into Bacon Canyon and the Gold Summit Mine further south. These mining sites, alongside seasonal drainages like Sonoma Creek and Willow Springs Canyon, reflect the late-20th-century character of Nevada’s high desert, where industrial extraction and natural topography meet along precise county boundaries.
