Discover the Secrets of Deep Time in McInnis Canyons NCA


Raft the river with CCA’s very own paleontologist, Rob Gay, and learn about the billions of years of history written in the rocks. From the earliest dinosaurs to Ice Age mammoths, this scenic area encapsulates a vast timespan of life on the planet. Journey on trails to find evidence of massive geological cataclysms and explore rugged canyons for traces of prehistoric deserts fiercer than the Sahara. All while enjoying the unparalleled hospitality of CCA's renowned guides and experts.

Enjoy locally sourced custom catered meals throughout the day freshly by our expert guides. Spend your evening talking about the geology of the canyons while sipping local wine and beer under the amazing night sky.  This one of a kind adventure awaits the curious adventurer!

"I love beautiful late summer days. The leaves showing the first hint of fall's change. Rippling waters, towering red rocks. The lonesome sound of a train in the distance and ancient traces where dinosaurs once roamed. All of these and more await you on our signature CCA adventure, "The Colorado River Rocks." This trip is a spectacular two day/ one-night adventure into the heart of the canyon stronghold of Ruby-Horsethief."

- Rob Gay, CCA Education Director and Paleontologist
