State wildlife officials captured 40 bison using net guns fired from helicopters during a relocation effort on the Henry Mountains near Lake Powell. The bison, which were captured Jan. 15 and 16, were then given a heath checkup and prepared for transportation to the Book Cliffs in northeastern Utah. Thirty bison were moved from the Henrys to the Book Cliffs last winter.
