Photos of the barrell transfer are in Dorman's book on Salida. Al Chione currently has a slide set (set M-2) on salida that has shots of the barrell transfer in action. Availablity of this set ends on January 15, 2001. Also see the Trails Along the Columbine series of books by Sundance. There is a book on Salida only and has coverage of this transfer.
