They don’t call it “The World’s Highest Junkyard” for nothing as empty oxygen bottles litter the ground en route to the summit, 29,028 feet above ground. With all due respect, the crowded climb is a tremendous feat for anyone. And don’t even get me started on how amazing Sherpas are (many of which climb without oxygen while carrying tourests’ gear). For more info, Jon Krakauer first-hand account of the climb, Into Thin Air, is one of the most engaging and profound books on the subject — not to mention humanity — you’ll ever read. Highly recommended.
