Silver City sits at the southern edge of this landscape, where the foothills meet the Lewis and Clark Range. The area is defined by a sophisticated system of water management and drainage, with numerous irrigation channels such as the Gans Klein Ditch, Vincent Ditch, and Justisson Ditch crisscrossing the lower elevations near Willow Cr and Silver Cr. These features indicate the agricultural importance of the valley floors below the mountain peaks.
