The San Juan River corridor anchors this 1980 survey of the Four Corners region, where industrial development and ancestral lands meet. The map documents the significant energy infrastructure of the late 20th century, notably the Navajo Mine, San Juan Coal Mine, and Jewett Valley Coal Mine, which flank the river west of Farmington. This industrial footprint is situated within the Navajo Indian Reservation, while the northern reaches of the sheet extend into the Ute Mountain Indian Reservation across the Colorado-New Mexico state line.
