Gerlinde Kaltenbrunner's interest in mountain climbing developed while she was growing up in Spital am Pyhrn, Austria. At the age of 13, Kaltenbrunner ventured up her first major peak, "Sturzhahn," a 2,028-meter (6,654 foot) climb. After that experience she rarely skipped an opportunity to go climbing. Her greatest dream—climbing an 8,000-meter (26,247 foot) peak—came true at the age of 23, when she succeeded in climbing the fore-summit of Broad Peak in Pakistan, at a height of 8,027 meters (26,335 feet). She then put the money she earned as a nurse into different trekking and climbing expeditions to the Himalaya. After climbing the Nanga Parbat—her fifth 8,000-meter peak—in 2003, she decided to become a professional mountain climber. Today, National Geographic Explorer Gerlinde Kaltenbrunner has climbed all 14 main peaks in the 8,000-meter series. When she reached the summit of K2 (8,611 meters or 28,251 feet), she became the first woman to scale all 8,000-meter peaks without supplementary oxygen. In 2012, Kaltenbrunner was named National Geographic Explorer of the Year.


  • Several unsuccessful attempts of climbing K2, and deciding to try one more time (start-4:20 min.)
  • Animation: the route up K2 (4:21-4:52 min.)
  • How weather influences decisions on a climb (4:53-5:44 min.)
  • Unable to make the ascent: Ralph (Gerlinde's husband) turns back (5:45-7:25 min.)
  • Continuing onward and upward: battling snow and wind (7:26-9:10 min.)
  • Difficulties on the final ascent: spin drifts and avalanche danger (9:11-11:01 min.)
  • Oxygen at 8,000 meters: giving themselves time to adapt by camping one more night (11:02-12:01 min.)
  • A dream come true: perfect conditions, willpower, and teamwork allow for a successful summit (12:02-14:33 min.)

Strategies for Using Video in a Variety of Learning Environments

  • Have students preview several of the videos and choose the one they find most inspiring. Have students describe in writing a conversation they might have with the speaker(s).
  • Freeze the video on a relevant image. Have students observe details in the still image and jot down predictions of what the full video might address. Discuss students’ ideas before and after watching the video.
  • Pose an open-ended question before students watch the video, and have them discuss their ideas before and after in small groups.
  • Have students determine what they think the key message of this video is. Was the speaker effective in getting his or her message across?
  • Show a short clip to engage students during class, and then have students watch the full video at home and write a paragraph responding to the content or a question you give them.
  • Have students note statements that represent facts or opinions, including where it’s difficult to tell the difference. What further research might help distinguish facts and opinions? How might the speaker’s viewpoint compare with others’ viewpoints about a topic?
