Atfalati
The Atfalati [aˈtɸalati], also known as the Tualatin or Wapato Lake Indians are a tribe of the Kalapuya Native Americans who originally inhabited and continue to steward some 24 villages on the Tualatin Plains in the northwest part of the U.S. state of Oregon; the Atfalati also live in the hills around Forest Grove, along Wapato Lake and the north fork of the Yamhill River, and into areas of Southern Portland.
The Atfalati speak the Tualatin-Yamhill (Northern Kalapuya) language, which is one of the three Kalapuyan languages.
