Alex Honnold Climbs a Glacier (Full Episode) | Arctic Ascent | National Geographic
By National Geographic
Key Concepts
- Big Wall Climbing: A style of climbing that involves multi-day ascents of massive rock faces, requiring specialized gear, hauling systems, and camping on the wall.
- First Ascent: The first successful climb of a route or mountain that has never been summited before.
- Choss/Chossy: Climbing slang for poor-quality, loose, or crumbling rock that is dangerous to climb on.
- Pitch: A section of a climb between two belay points.
- Head Wall: The steep, often vertical or overhanging final section of a cliff.
- Glacial Calving: The process where chunks of ice break off from the edge of a glacier, often creating icebergs.
- Daugaard-Jensen Glacier: A massive, 40-mile-long glacier in Greenland, studied for its movement and stability in the context of climate change.
1. Main Topics and Objectives
The video documents an expedition to Greenland to perform the first ascent of Ingmikortilaq, a 4,000-foot sea cliff. The expedition had two primary goals:
- Climbing: Alex Honnold, Hazel Findlay, and Mikey Schaefer aimed to summit one of the world's largest unclimbed rock faces.
- Scientific Research: Dr. Heïdi Sevestre conducted research on the nearby Daugaard-Jensen Glacier to determine if it is accelerating its ice loss due to climate change.
2. The Climbing Challenge: Ingmikortilaq
- Scale: The wall is nearly 4,000 feet high—1,000 feet taller than El Capitan and three times the height of the Empire State Building.
- Conditions: The team faced "nightmare" conditions, characterized by extremely loose, "chossy" rock that posed a constant threat of rockfall.
- Logistical Hurdles: Due to bad weather, the team was separated from much of their gear, forcing them to improvise with limited equipment (e.g., only one pair of climbing shoes for the team initially).
- Team Dynamics: The extreme danger led to a morale crisis. Mikey Schaefer, citing the unacceptable risk of loose rock and lack of proper gear, decided to stop climbing, leaving Alex and Hazel to complete the final push.
3. Scientific Methodology
- Data Collection: Dr. Sevestre used drones to map the glacier's front and time-lapse cameras to track movement.
- Research Goal: By comparing current movement data with records from two decades ago, the team sought to understand the glacier's contribution to sea-level rise.
- Findings: Contrary to expectations, the Daugaard-Jensen Glacier was found to be relatively stable, moving at approximately 25–30 feet per day—the same speed as 20 years ago.
4. Key Arguments and Perspectives
- Risk Assessment: Mikey argued that "there isn't enough value" in continuing when the risk of injury from rockfall is high and the gear is inadequate. He emphasized that "you can only roll the dice so many times."
- Optimism vs. Reality: Hazel challenged Alex’s inherent optimism, noting that his drive to reach the summit sometimes blinded him to the objective dangers of the wall.
- Environmental Stewardship: Alex expressed an "innate optimism" regarding climate change, arguing that solving environmental issues would inherently improve the quality of human life.
5. Notable Quotes
- Mikey: "It’s like literally getting shot at by your buddy." (Referring to the danger of rockfall caused by the lead climber).
- Hazel: "I need to know that you’re thinking clearly about it... I’m definitely more risk-averse than you."
- Alex: "The most important part of climbing the wall for me is just staying in the moment... focusing on 'Can I do this move?'"
6. Synthesis and Conclusion
The expedition was a success on both fronts. Alex and Hazel reached the summit of Ingmikortilaq after navigating a dangerous, crumbling head wall, proving that the climb was possible despite the lack of ideal gear. Simultaneously, the scientific team discovered that the Daugaard-Jensen Glacier remains a rare, stable exception in a rapidly warming Arctic. The project highlights the intersection of extreme human endeavor and environmental observation, concluding that while some natural systems are holding strong, the broader trend of climate change necessitates urgent global action.
