In this episode of Explore, podcast host David McGuffin speaks with Canadian climber and expedition leader Shira Biner, who led the first female-plus team to establish a new 600-metre route on Eglinton Tower in the remote fjords of Baffin Island. Biner recounts the 2025 expedition, which was partly funded by The Nat Gillis Adventure Photography Expedition Grant awarded by the Royal Canadian Geographical Society.Over 29 days, the team travelled entirely under human power, skiing 150 kilometres across Arctic sea ice with teammates Kelly Fields, Heather Smallpage and Nathalie Afonina to reach the towering granite walls of Eglinton Fjord.From navigating crevassed ice and polar-bear country to sleeping on narrow ledges high above the fjord, Biner shares the physical and emotional demands of exploratory climbing at the edge of the world.Through her work as an expedition leader and a climber, Biner explores the intersection of human-powered travel, alpine climbing and geographic discovery. Based in Squamish, B.C., she approaches mountaineering as both an athletic pursuit and a form of storytelling. In 2023, Biner received an RCGS Expedition Grant to support an alpine rock-climbing journey on the east coast of Baffin Island. In 2025, she received the RCGS Nat Gillis Adventure Photography & Expedition Grant, recognizing her leadership and visual storytelling in the North.Topics covered:* The 2025 Baffin Island expedition and first female-plus ascent of Eglinton Tower* Skiing and hauling gear 150 kilometres across Arctic sea ice* Climbing with Kelly Fields, Heather Smallpage and Nathalie Afonina* Team dynamics, leadership and risk management in remote climbing* The legacy of the late Natalie Gillis and women-led exploration* Why human-powered travel remains central to adventure and storytelling
