The Washburn map is for sale on the streets of Kathmandu. Bring also a small compass. Use it to take a bearing from C4 to the wall when going for the summit. There are no ropes on this section and people have been lost on their way down when clouds or night set in. Much of the tragedy in 1996 could have been avoided if people had found their way back to C4. Sometimes, strobe light is used by expeditions on C4 for direction in foul weather on descent. Another option is the use of a small, handheld GPS unit. Do use some of the options, and fix ropes wherever possible.
