Aquinnah (Gay Head) Cliffs

The westernmost point of Martha's Vineyard, the Aquinnah Cliffs rise roughly 150 feet of layered clay deposited when the Laurentide ice sheet retreated thousands of years ago. The cliffs sit on tribal land belonging to the Wampanoag, whose ancestors have lived here for some 10,000 years. You are not permitted to climb them or remove clay. Go anyway — the land makes the rules clear.
