Redwall Cavern

Grand Canyon National Park

Located at a large bend in the Colorado River within Marble Canyon, a massive natural amphitheater has been carved into a towering limestone wall. In August of 1869, Major John Wesley Powell and the men of his expedition camped here. In his journal, Powell, who was prone to exageration, estimated that 50,000 people could comfortably fit into the cavern, and while this may be a bit of an exageration, it illustrates how massive the cavern actually is. Redwall Cavern is located at river mile 33 in Grand Canyon National Park.
