The name was not drawn from a hat! ;) Zion National Park, Utah, USA; pic taken from an overlook on the way to the Zion Tunnel on Utah State Route 9. These collapse arches are a common failure mode in the massive Navajo Sandstone as it's undermined by erosion. There is a trail to an overlook at the low point to the right of the arch. The trailhead is right by the eastern portal of the tunnel.
