According to Theodore Roosevelt, the Grand Canyon is “the one great sight which every American should see”. Mather Point is one of the most popular views of the Grand Canyon, and seemed to be the best place to stop as our daughter stamps her 16th National Park in her National Park passport book. From Mather Point visitors catch glimpses of the Colorado River which, over the course of anywhere from six to seventy million years, carved out a sizable portion of earth. From Mather Point it is exactly ten miles across the Grand Canyon to the North Rim and a mile deep to the muddy river below. The Grand Canyon isn’t just getting deeper over time, but wider too. You can see columns of land that appear to be one freeze or one plant root away from toppling into the canyon. And a view of Mather Point reveals that this particular viewing area will have the same fate.
