In the book Into Thin Air I've read through chapter seven (pg. 105). After reading through this amount of the book, I was most curious about the conditions of the lodgings that the travelers stay in on their way up Everest. In one of the chapters in the book, they describe a filthy, dilapidated shack they had to stay in, that even made some of the travelers sick. In another passage, Krakauer describes a very nice and clean village, with fresh water, food, and heating. After some research, it was confirmed that the lodging on Everest ranges from respectable to derelict, very much like in the book.
