Resurrection / Superposition Rapid, Colorado River

In an ironic geomorphic situation, the Colorado River has formed a new rapid downstream from the mouth of the Grand Canyon near Pierce Ferry. Here, recession of Lake Mead has (obviously) induced incision by the river. The river adopted a new course that traverses some resistant beds in the Muddy Creek Formation. This video chronicles the vagaries of this rapid.
