Native American heritage sites are sites specifically created in many National Park Sites in the United States to commemorate the contribution of the Native American cultures. The term ‘Native American’ includes all cultural groups that predate the arrival of either western European or East coast explorers and settlers. In this sense, Native Alaskans of both arctic and sub-arctic cultures are included with the American Indians of the continental United States. Native Hawaiians are included as the traditional cultures of the islands.
