According to the informational sign at the visitors center at Box Canon Falls
Nearly 2 Billion years ago, in the Precambrian Era, the foundation of the Rocky Mountains was laid down. At the time the oldest rocks in the Ouray area were formed—the quartzite found in Box Canon
Throughout geologic time, many faults or cracks formed in the Ouray bedrock. Approximately 220 million years ago a massive fault began to form at Box Canon. Over millions of years the hard Precambrian rocks on the south side were thrust up, while the soft sedimentary rocks on the north dropped down. More recently, alpine glaciers began to carve an opening for the falls.
The Canon continues to erode by the powerful force of water in canyon creek. The fastest water easily washes the soft sedimentary rock away. Sand and gravel slowly grind down the harder rock. The turbulent water at the falls actually plucks out bits of rock. It is this force of water that will continue to play the lead role in Box Canon’s future.
