The San Juan Mountains dominate this 1950s era survey, where the Continental Divide weaves through high peaks and national forests. High-altitude mining history is etched across the landscape at the Summitville Mine and Asiatic Mine, while the Denver & Rio Grande Western RR provides a critical transportation backbone connecting mountain settlements like Silverton and Telluride to the valley floor. To the south, the Southern Ute Indian Reservation and Jicarilla Apache Indian Reservation cover significant territory near the border of Colorado and New Mexico.
