I've often heard that it is the altitude and exposure that makes Everest most challenging, but technically speaking, it's not a very challenging climb at all. Supposedly, if base camp for Everest were at sea level, then summitting Everest, for the most part, would be a simple walk up to the top.
What would the different sections of Everest be rated using the Yosemite decimal system? (i.e. Trek into base Camp, Khumbu Icefall up to Camp 1, Camp 1 to Camp 2, Lhotse Ice face, Yellow Band, Hillary Step, etc...)
Note: The accepted answer will preferably do something cool like; list of all the sections of the climb to the summit and their classes, draw a rad doodle with arrows and labels, make a piechart, etc... Links to articles or other posts will only get upvotes.
