Our Mount Rainier climb that summitted yesterday reported fantastic conditions on the Muir route. They noted that the route up the Disappointment Cleaver is in excellent condition, and they were able to pull some of the fixed lines from the route that had been in place since early season.
Snow conditions lower on the mountain are still very good, so we are not yet needing to use our trail shoes on the portion of the climb just out of the Paradise parking lot.
