Smith involved himself in archaeological work, and began by digging in the Thompson River district of British Columbia in 1897. In successive years, he worked a little farther east, and also around Puget Sound, and down the west coast of the state of Washington.

One small section east of the city of Vancouver was found to reveal traces of a people with a much more highly developed technology than others of the region. Some of the regions explored revealed the remains of coast tribes, others of interior tribes. At some points these characteristics merged, producing a different type.
