The Dolores River valley and the high desert plateaus of Montezuma County are defined by a complex network of irrigation infrastructure designed to sustain agricultural life. Extensive water systems such as the Main Canal Number 1, Highline Ditch, and Upper Hermana Lateral dominate the landscape, gravity-feeding water from the McPhee Reservoir and Narraguinnep Reservoir to the surrounding farms. This modern survey illustrates the proximity of the northern outskirts of Cortez to the historic settlement at Lebanon, showing how rural road grids have expanded around traditional land boundaries.
