Among his works are two National Park Service building complexes at Mt. Rainier National Park, both designated National Historic Landmarks:
In 1932, Ernest A. Davidson pondered the result of development in Mt. Rainier's Yakima Park, noting it could be classed as a failure "since the area is far less attractive" than before construction, or it might be considered a great success "since the general appearance and result is far superior to those other developments with which comparison may be made, and 'just grew' like topsy".
