2023 Map of Nichols Reservoir

About this map

The vast volcanic landscape of Craters Of The Moon National Preserve dominates the southern reaches of this modern Idaho survey. The terrain transitions from the high, relief-heavy ridges near Timbered Dome Creek in the northwest to the expansive, relatively flat high desert plains of the Snake River Plain. This area illustrates the critical intersection of natural wilderness and human engineering, as seen in the linear paths of the Blaine Canal and Moore Canal, which draw water across the arid Butte County landscape. These irrigation features stand in contrast to the seasonal drainage of Champagne Creek, highlighting the region's managed water network. The map also documents the passage of modern transit via Highway 20 26 and 93, which intersect this rugged portion of the Intermountain West.
