About this map

The Humboldt River corridor dominates this high-desert landscape near the Lander and Eureka County border. The map documents a critical transportation and irrigation node where the northern Boulder Flat and Boulder Valley meet the rising elevations of the Shoshone Range. Settlements like Dunphy, Shoshone, and Rixies are situated along the valley floor, supported by an intricate network of water management features including the Blue House Ditch, Rose Canal, and the Rock Cr Ditch.

South of the river, the terrain shifts dramatically at the Argenta Rim, leading toward higher ground at Shoshone Point and the passage at Dunphy Pass. This 2021 update from the U.S. Geological Survey illustrates the modern configuration of the T-S Rd and the vital riparian areas of the Blue House Slough, capturing the essential balance between the arid rangeland and the managed waters of the Humboldt.
