Article Additions
editI added information about the Challis Arc's length and geographic position. The article had only one source prior to my edit; that source said subduction was the method of formation for the Challis Arc. I added other theories that have been proposed concerning the Challis Arc's tectonic history. A picture of the North Cascades was also added.
