High in the mountains of southwest Yukon, as far west as one can go in Canada, lies Kluane National Park and Reserve. The park is home to the country’s highest peak, the 5,959-metre Mount Logan. From its earliest documented ascent, in 1925, Mount Logan has been a continuously productive site for the advancement of scientific knowledge. Our guests on today’s episode, Dr. Zac Robinson and Dr. Alison Criscitiello, talk to us about the goal of their expedition which is to drill ice core samples from the summit plateau, and to re-take landscape photos from previous climbing expeditions, many of which are held here at LAC. Our colleague Jill Delaney also discusses repeat photography and gives us more details as to how LAC’s photography collection can be used by the public.
