Ryan Waters is an American mountaineer, guide, polar adventurer and speaker. In 2014, he became the first American to complete the Adventures Grand Slam, by climbing the Seven Summits and skiing full, unsupported trips to the North and South Pole.[better source needed]
He has guided all of the Seven Summits and has either guided or personally climbed 5 different 8000 meter mountains including Everest (4 times), Manaslu (3 times), Lhotse (2 times), Cho Oyu (2 times), and Broad Peak. He has also attempted K2, Gasherbrum II, and Dhaulagiri.
A team unsupported West to East ski traverse of Greenland expanded his interests into the polar regions. In January 2010, Ryan and Cecilie Skog completed a "nice long ski tour" in Antarctica. The team skied 1,117 miles/1,800 kilometers over 70 days from Berkner Island in the Filchner-Ronne Ice Shelf to the South Pole, then continued to the Ross Sea and set a new record by completing the first ski traverse of Antarctica without resupplies or the use of kites.
He and fellow explorer Eric Larsen reached the North Pole on May 4, 2014 after skiing unsupported for 53 days from Cape Discovery, Canada. This expedition was made into a 2-hour documentary titled Melting: Last Race to the Pole, for Animal Planet television network.
In 2016, Ryan guided 3 clients on an unsupported full length ski trip to the South Pole via the Messner/Fuches route over a 44 day expedition. This is thought to be only the second time that a full length unsupported expedition has been guided taking clients to the South Pole.
He is considered to be the premier guide in the world who is equally versed in leading High Altitude mountain climbing and Polar Ski expeditions. To date he has guided clients 47 times to the summit of the various 7 summit peaks.
