Dave Hahn

In 1999, Hahn, who specializes in guiding high, glaciated mountains, led the team that discovered the remains of celebrated English climber George Mallory at 27,000 feet (8,200 m) on Mount Everest's North Face. Mallory died on the mountain in 1924, along with fellow climber Andrew Irvine, but it has never been determined whether or not he first reached the top.

Numerous organizations use Hahn as a guide including Rainier Mountaineering (for which he has worked since 1986), and Fathom Expeditions. Hahn is a regular guide on Mount Rainier in Washington with more than 270 ascents, as well as a professional ski patroller at Taos Ski Valley in New Mexico where he has been employed since 1985. He has guided climbers to the summit of Cho Oyu twice, the sixth-highest mountain in the world, bordering Nepal and Tibet. Hahn has also guided former New Mexico governor Gary Johnson to the summits of Vinson and Mt. Everest.

Hahn graduated with a Bachelor of Arts degree in history from the State University of New York at Buffalo in 1984. In 2014, he was inducted into The State University of New York at Buffalo Sports Hall of Fame.

David Allen Hahn (born November 3, 1961, Okinawa, Japan) is an American professional mountain guide, ski patroller, journalist and lecturer. In May 2013, he reached the summit of Mount Everest for the 15th time—the most for a non-Sherpa climber, according to Outside Magazine contributor and climber Alan Arnette. Among Hahn’s other notable accomplishments are his 35 summits of Vinson Massif, Antarctica’s highest mountain. He has reached the summit of Denali in Alaska, North America’s highest peak, 21 times over the course of 30 expeditions.

Hahn has also made a specialty of guiding the "Shackleton Crossing" on South Georgia, the island in Antarctic waters that figured prominently in the Endurance saga of 1914-16., a trip that earned the designation as Trip of the Year from Outside Magazine in 2004.
