This arch, inside a wind-eroded cave, is a popular shot for photographers, who must squeeze in to take the picture.
The state park in which the arch and cave are located, founded in 1934, also contains 2,000-year-old petroglyphs — showing, among other things, hunters using atlatls — and hosts an annual competition in which participants compete using the ancient weapons.
