The Omineca Arc or Omineca Belt was a Jurassic through Cretaceous volcanic arc terrane in western North America, extending from Alaska through Yukon and British Columbia to Washington. The Omineca is bounded by the Foreland Belt to the east and the Intermontane Belt to the west. It is named after the Omineca Mountains of north-central British Columbia.[http://www.washington.edu/burkemuseum/geo_history_wa/The%20Omineca%20Episode.htm The Omineca Episode (180-115 million years ago)]
