In the frozen heights of Canada’s tallest peak, an international team of scientists launches a daring expedition to unearth thousands of years of climate data in one record-breaking ice core. Glaciologist and National Geographic Explorer Alison Criscitiello is the brain and brawn behind this ambitious quest. As she leads her team on a 10-day climb up the mountain, through whiteout conditions and precarious icefalls, Ali and her team defeat the odds and reach Mt. Logan’s summit plateau where they camp for 16 days, while drilling in frigid conditions.
