Welcome to Black Canyon of the Gunnison National Park
The Colorado Rockies are known for their mountains, but the Black Canyon of the Gunnison National Park is the inverse geographic feature – a massive yawning chasm etched out over millions of years by the Gunnison River and volcanic uplift. Here a dark, narrow gash above the Gunnison River leads down a 2000ft chasm as eerie as it is spectacular. No other canyon in America combines the narrow openings, sheer walls and dizzying depths of the Black Canyon, and a peek over the edge evokes a sense of awe (or vertigo). In just 48 canyon miles, the Gunnison River loses more elevation than the entire 1500-mile Mississippi. This fast-moving water, carrying rock and debris, is powerfully erosive. Without the upstream dams, the river would carry five times its current volume.
