The second area to move quickly through is under the Tsunami Wave serac. This feature is above the traverse toward the Emmons Shoulder above the Cleaver. The serac is leaning steeply over the route, and ice has been calving off the underside periodically. Rangers noticed fresh icefall debris this morning over the trail under this serac.

Icefall can happen at any time of day on Mt. Rainier. However, minimizing your time under icefall zones can help mitigate this hazard. Also, moving efficiently and relying on good time management amongst your team can help you get out from under these icefall zones before the heat of the day.
One last area of note for climbers on the DC is the bergschrund at 13,800 ft. Here, a very large snow bridge spans an even bigger crevasse, and the route ascends the steep uphill wall of this crevasse. A hand line is in place here to help climbers negotiate this steep feature. This area is also creating quite the bottleneck on busy days. Please come up with a plan within your team before climbing that will allow you to safely and efficiently negotiate this hand line. Keep the rope streched out between team members as you descend the hand line. Below the bergschrund, the snow bridge is large and flat. Though it looks like a good place to stand and wait, it is not. Underneath this bridge is the largest crevasse crossed by the route.

Remember, be courteous to other climbers you find on the mountain. Communicate when you need to pass other rope teams, and remain patient. Climb safely and make new friends on the mountain this week!
