Sid Pattison


Sid has been skiing and climbing in the mountains for close to 20 years. Since cutting his teeth in the Cascade mountains, skiing and climbing have taken him to New Zealand, Europe and Alaska along with the many great ranges of the lower 48 where he has completed technical ascents and descents on ice, snow and rock. Sid is continually seeking out the obscure, remote and committing lines destined to be classics. Sid lives in Winthrop, Washington with his wife and two daughters. Sid has more recently led 2 of our Unclimbed Peak expeditions in Nepal as well as successfully guided our Lhotse expedition last spring. Sid is currently guiding a private climber on our Mount Everest expedition.
