Re: Mt Jefferson in the central Oregon Casades.

Ok. I won't say much about it, except that the summit pinnacle is pretty rotten rock. I am told that there is a route that goes over pretty solid rock (class 5), but I didn't find it. The way I went up was class 3, but rotten. There are approaches over the one glacier (Whitewater?) that aren't bad for soloing (it gets skied a lot). You might get current info at www.cascadeclimbers.com/ . Or ask at mtncommunity.org - one of the frequent posters there lives in Portland.
