As the aircraft did not arrive in Salt Lake City, SAR operations were initiated but no trace of the aircraft nor the pilot was found. Eventually, Ward Mortenson and Elburn Orton, two youthful sheepherders, found the wreckage of the aircraft on 24 June 1930 some 22 miles south of Cedar City, in the Kanarra Mountains.
