Carrie and Molly begin summit day early, traveling cross country up the slabs below the Quien Sabe glacier. They make an interesting discovery from years past and learn about a new mountaineering style for their soft shell pants. Lead by their guide, they travel on bare glacial ice and navigate a maze of crevasses. Molly experiences a revelation regarding snow bridges and the sisters compare their emotions while traveling in this new terrain. They contrast hiking on a trail vs traveling on a glacier and climb alpine rock up to the summit of the peak!
