Route info on Lib Ridge as of last weekend.
Getting on the ridge will become problematic as the burg will open up in the next few weeks. Don't linger crossing the Carbon glacier - we witnessed two massive avalanches sweep way down. Lots of loose rock below the Thumb - traverse early in the morning. Also, last 200 feet below Thumb Rock is very icy! Don't be shy using your ice tool(s)- we went with one tool and one ice axe which worked well. We had good conditions for most of Sunday. Did close to 1000' of easy (40 to 50 degrees) ice climbing. There are two steps (10' to 15' vertical each) at around 13,200' - 13,400' that can become difficult as the snow melts out. Great route but go as soon as the weather will allow.
