Cohab Canyon - Cassidy Arch Trail Professional Review and Guide
"Sixty-five million years ago, while forces inside the earth were pushing up the Colorado Plateau, a 100-mile-long wrinkle in the earth's mantle was formed in southern Utah. Thousands of feet of subterranean sedimentary rock was forced upward as the fold developed, twisting and buckling to form a convoluted range of mountains we now call the Waterpocket Fold.
Today, after a great deal of erosion, the mountains rise less than two thousand feet above the desert floor, but what remains is a fairyland of geologic sculpture. The ancient mountains, most of which are now part of Capitol Reef National Park, have been carved into a tangle of hidden canyons, monolithic spires, and towering cliffs. The hike described here starts in the Fremont River Valley, near the pioneer settlement of Fruita, and crosses a portion of the Capitol Reef to Grand Wash. It offers a good representation of the unique landscape of the Waterpocket Fold."
