In the gully I traversed by constantly switching from one ramp to another-these ramps made it a very reasonable third class the entire way. There were only about three difficult class three moves. The main risk was that if another person were above me he would trigger high velocity rockfall that my helmet could not withstand. If you travel with others you must travel together and move extremely carefully. You will need to slow to the speed of the slowest person in the group.
Helmets are a necessity.
Rope is not needed. At the final 50 feet the gully reduces its angle to a 20 degree slope. You will really enjoy the summit view and the ancient register with prominent mountaineer's signatures.
