Why the Roaring Fork River Was Once Called the Thunder River

Before Aspen and Snowmass became world-famous destinations, the Roaring Fork River was known by another name — the Thunder River. This powerful name was given by the Ute Native Americans who lived in the valley long before modern rafting began. Today, Thunder River Adventures proudly carries that legacy forward, offering guests a chance to experience the same spirit, power, and beauty that inspired the name.
