From the beginning of the wolf recovery in Yellowstone, wolves have favored the Stillwater River as a travel route through the rugged mountains, as well as part of their home range. The Soda Bute Pack spent almost a year in the Stillwater and on the adjacent Beartooth Front. Number 27 denned and bore a litter of five pups in the area; and on June 10, 1997 one of the Sawtooth yearlings who had probably migrated down the Stillwater was shot as she was attacking sheep on the Beartooth Front.
