Question

"No temple made with human hands can compete with Yosemite," wrote John Muir, whose crusading led to the creation of the California park in 1890. Over four million visitors come to this temple annually, most of them spending time in the Yosemite Valley. This mile-wide, 7-mile-long canyon was cut by a river and then widened and deepened by glacial action.
