Everest - Buddhists believe a goddess lives in the mountain and she decides who summits, who doesn't, who makes it down safely, and who doesn't. She doesn't take kindly to big egos or those who try to "conquer" her. Humble respect always.
This is the Tibetan side of Mount Everest where tents are pitched in deep snow. This is how they had their tents set up in the book, and this helps me visualize the setting and scene of the book better.
