Geocache Description:

The Hurricane Fault marks one of the edges of the Colorado Plateau. The steep walled canyons of Zion National Park and Kolob Canyons are the direct result of this fault.

There is ample parking in the visitor center parking lot. No entrance fee is required as long as you don’t go any further into the park.

The Colorado Plateau is a geomorphologic feature that covers parts of Utah, Colorado, New Mexico, and Arizona. About 15 to 20 million years ago the entire Colorado Plateau began being uplifted in one relatively undisturbed mass. This particular fault can be traced about 155 miles south to the other side of the Grand Canyon. In many places faults at its edge created sheer cliffs as the Plateau was uplifted. In the area of the park, the Colorado Plateau has been pushed up about 3,600 feet. Erosion has removed much of that material.

This uplift significantly increased the erosive power of the rivers and streams of the park. The water in these rivers was now flowing down from a higher elevation and as a result cut down into the underlying rock faster. Here in Zion and Kolob Canyons, the surrounding bedrock is cohesive so as the rivers erode down steep walled canyons are formed.
