The Black Canyon of the Gunnison (Images of America)

The Black Canyon of the Gunnison River is one of the deepest, narrowest, and most inaccessible canyons in the United States. Very few explorers have ever traversed the 53-mile gorge in Gunnison and Montrose Counties. The canyon, one of the nation’s wonders, has been the precipitous stage for an exciting history featuring Ute Indians, a narrow-gauge railroad, sensational explorations, and the construction of the Gunnison Tunnel—the first major Bureau of Reclamation project in history. The Black Canyon became a national monument in 1932 and a national park in 1999. Today it remains a crown jewel of Colorado’s Western Slope.
