Black Rapids Glacier, Alaska Range, 1996

"Payoff for all the planning, all the aches and pains—a revelation of ice, rock, and sky greets the cyclists as they descend a thousand feet [305 meters] to Black Rapids Glacier. As a matter of pride and technique, they sought to avoid 'dabs'—putting a foot down for balance. They were doubly wary of 'endos'—pitching headlong over handlebars."
