DescriptionGay Head clay cliffs 4 of town of Aquinnah, Martha's Vineyard, USA.JPG
English: Martha's Vineyard's Gay Head clay cliffs - a piece of art over 100 million years in the making, are the end result of glacial deposits. According to local Native American Wampanoag myth and theology, these cliffs were considered sacred. The Wampanoag's major deity, Moshup, resided in these cliffs. Today, the use and protection of the cliffs and their clay is under the control of the local Wampanoag tribe in Aquinnah.
