[TR] Mt. Rainier - Disappointment Cleaver 6/12/2016 in Mount Rainier NP Posted June 14, 2016 · Edited June 14, 2016 by Autoxfil It was pretty much all step-across and end-runs. There were a couple "saggers" that were not obvious. I would solo it personally, but you would just need to be real heads-up. In general, the guide services really do a killer job of setting a safe route. I'm also very inexperienced on glaciers. Maybe dont trust my take on conditons.
