Mike and Jason head down to Zion National Park to take on one of the most famous big wall routes in the world the Moonlight Buttress. Towering 1200 feet over the valley floor, the Moonlight Buttress offers pitch after pitch of exposed crack climbing in one of the beautiful parks in the country. After a hard day of climbing, and a sleepless night on the wall, the boys have to dig deep to make the final ascent.
