The core of the mountain with Alison Criscitiello

Explore: A Canadian Geographic podcast

Few people have been to the summit of Mt. Logan, and even fewer people have been to the summit and stayed for more than 24 hours. But for the sake of science, RCGS Fellow and world-leading ice core scientist Alison Criscitiello and her team took 10 days to summit Canada’s highest peak, where they camped for 16 days.

In her new documentary, For Winter, Criscitiello takes viewers on a gruelling journey to the top of Mt. Logan, where she and her team of six researchers extract the longest ice core ever drilled at a high altitude: 327 metres. The goal was originally to drill 250 metres, but the team was able to go deeper, successfully extracting an additional 77 metres of valuable data about our climate and environmental history.

For Winter premiered at the Banff Film Festival this past fall and was produced by National Geographic. Along with being a National Geographic Explorer, Criscitiello is also the director of the Canadian Ice Core Lab at the University of Alberta and a leading high-altitude mountaineer who has led expeditions (many of them all female) up some of the world’s highest peaks. In this week’s episode, we get into her early days as a US Park Climbing Ranger in the Pacific Northwest and her journey into ice core science, which has taken her all over the Arctic, the Antarctic and many fascinating places in between.
