Big Horn Canyon is a national park located on the Montana-Wyoming border.  The park includes the Bighorn River, Big Horn Lake and some stunning canyons.  Part of the park is also located on the Crow Reservation.  One of the more unique features of the park is the Pryor Mountains Wild Horse Range.  This range is a refuge for a herd of free-roaming mustangs.  Pauline and I spent the day in the park with good friends taking in the spectacular scenery and getting to see many of the wild horses.
