Half Dome, turned red by the twilight glow, towers over the Merced River in Yosemite National Park, California. Half Dome, 8836 feet (2693 meters) tall, is a granite dome that seems to be missing a large section. While named Half Dome, the missing piece is likely a quarter, rather than half. Scientists believe the missing granite also eroded away as fast as it was exposed, rather than falling off in a dramatic event.
