A heavenly view

Our homepage image shows the stunning view from the North Rim of Grand Canyon National Park in the US state of Arizona. Can you see the rectangular hole in the canyon wall near the top of the image? That’s Angels Window. Brave hikers can make their way up to the trail above it, but the window itself is best viewed from various points along the North Rim. Far down below is the Colorado River. From about six million years ago, it gradually carved downward through countless layers of sedimentary, igneous and metamorphic rock. Even now, the Colorado and its tributary streams continue to deepen and widen the Grand Canyon.
