While it’s certainly a fairly big undertaking, don’t be too intimidated! You have trained for this, and you’ll be met at the top of the fixed lines with some of the most spectacular views you’ve ever seen in your life.
It takes most teams a good 1-1.5 hours to get to the start of the Headwall. The approach slope starts out fairly consistent, but rolls over a convexity before steepening to the start of the fixed lines. Heads up for some cracks that can lurk under that transition zone.
Rockfall hazard is mostly from climber's right and is significant enough to warrant putting that helmet you've schlepped up the last 8,000' on your head.
In recent years, there has been a well-defined bergschrund before the fixed ropes, sometimes called "The Eyebrow" for how it appears from 14,000' Camp. It can offer some protection from sloughs, although how much will often vary from year to year.
Descending the fixed lines is where climbers regularly have trouble. A commonly used technique to descend is to take a Sherpa Arm Wrap around the fixed rope for a self-belay, while clipping into the line with a locking carabiner on a cows tail. If someone is having an epic on descent, it can be quicker to lower them from anchor points, rather than fuddle with an arm wrap.
