Grand Canyon's rocks: Redwall Limestone, thick scenic cliffs formed from tropical seafloors

Explore the fascinating Redwall Limestone, one of the most prominent cliffs in the Grand Canyon. Join geology professor Shawn Willsey at Horseshoe Mesa near the Grandview Trail on the south rim as he explains the origin of this rock layer and the awesome bonus surprises it holds at Horseshoe Mesa, its rich copper deposits. The Redwall Limestone was deposited in the warm, shallow seas of western North America in the Mississippian Period, about 340 million years ago. This one of several videos on the Grand Canyon's rocks. Knowledge of the rock layers in the Grand Canyon is important to those who hike anywhere in the canyon, especially those hiking from rim to rim or day hiking deep into the canyon.
