This is a climb for experienced rock climbers and alpinists. Normally, the summit day is well over 12 hours long. While most of the climbing is on mid-5th class rock, there is one 5.9 pitch and several at a 5.8 standard. Add to this the challenge of technical rock at 17,000 feet above sea level and the alpine nature of the climb, and it amounts to a very demanding route. Climbers considering the ascent need to be solid 5.9 followers with experience on long technical routes of at least 10 pitches in length.
