Overview

About This Attraction

Dark canyon walls rise above the Gunnison, a knife-thin gorge carved into ancient rock. The Gunnison River shows the force of erosion as it chews through layered volcanic and sedimentary deposits, exposing two-billion-year-old basement rocks. This is erosion in action—a river cutting through uplifted bedrock to sculpt a 48-mile path that threads through the park.
