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.

Zion National Park, Utah, USA. Off Utah Route 9 en route to the tunnel.
