The Unai Dangkulo Petroglyph Site is one of a small number of documented rock art sites in the Mariana Islands.
Located on the northeastern shore of the island of Tinian in the Northern Marianas, it is the only such site composed exclusively of pictographs (that is, carved or pecked figures rather than painted ones).
The site is on a limestone outcrop that is sometimes covered by sand or cleared of sand by typhoons, and was discovered in 1998 after it was exposed by Typhoon Keith.
[2] The site was listed on the United States National Register of Historic Places in 1999.
