Where on Earth - May 2017

Clues for May 2017:

1. This arch, inside a wind-eroded cave, is a popular shot for photographers, who must squeeze in to take the picture.

2. 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.

3. The park lies in bright red Aztec Sandstone, deposited in the Jurassic, and the windswept cross-bedding of the former dunes can still be discerned in outcrops today.
