RANGELEY — Ed Webster will present “My Storm Years on Everest,” a photographic, personally-narrated PowerPoint lecture, at 6 p.m. Tuesday, Aug. 21, at the Rangeley Public Library.

In 1988 Webster, American mountaineer, achieved and survived the impossible. With three partners, he ascended a new, never-before-attempted route up Mt. Everest’s most dangerous isolated side in Tibet — and without the usual assistance of oxygen bottles, radios and Sherpa climbers to carry the necessary food and equipment.

Then, somehow, Webster led his partners down a storm-bound, avalanche-plagued, four-day descent off the mountain, without any food, badly frostbitten, and near death.

Sir Chris Bonington called Webster’s four-month Mt. Everest expedition “amongst the finest examples of survival in Himalayan mountaineering.”

Webster, a resident of Orr’s Island, has had his articles and photographs published in dozens of magazines and by Sierra Club Books and National Geographic. He will have his books and posters available for purchase and signing after the lecture.
