Hance Creek, when it flows, tumbles through this small pour-off in a corkscrew fashion. The total drop is only about six feet but the eroded and polished stone provide a fascinating pathway for the streaming water. It would be interesting to be able to watch the water as it flows down through the corkscrew passage. Something interesting in this panorama is that many of the rock formations of the Grand Canyon are represented at this location within just a few feet of each other. Some of the rocks have tumbled miles to reach this point, others originated perhaps just a few feet away. Let’s look at them starting at the upstream left in the foreground. We first see a piece of Vishnu Schist, the hard, black basement rock of the Grand Canyon. Just a few feet away is an angular chunk of Tapeats Sandstone. Its original position was the formation immediately atop the schist. A bit further to the right, and in the foreground, is the bright red-orange representative of the Supai Sandstone. Its journey has been a long one to get this far down the canyon. But, it has not travelled the farthest. The yellow-tan colored stone just to the right, and a bit behind The Supai stone, looks to be Coconino Sandstone. On the south rim, the Coconino layer lies nearly at the top of the canyon. Nestled behind the Coconino sandstone in this jumble of deposited rocks and boulders appears to be a small piece of limestone, presumably from the Redwall formation. The Redwall formation seems to be more dense than the Kaibab Limestone and so probably is less likely to break apart on its journey down the side canyons to the river.
