I am hoping to head out this coming winter/spring and climb some of your peaks. I have experience climbing in NE, several winter ascents of Washington, and the Presidentials, plus extensive experience hiking and camping in the winter. What I DON'T have is ANY experience at altitude, the highest I've ever been is Mt Washington. (Considering I live about 5 feet above the high tide mark that sure feels like a lot of altitude!) I'm figuring if I plan on taking a full day to stagger up to Camp Muir and plan on spending a few days there, hanging around, taking short hikes, practicing glacier techniques, etc. I'll be alright. Is my thinking solid or do I need to refine it? My other thought was flying into Portland and climbing Mt Hood first, then driving up to Seattle. I can devote about 10 days to this proposed trip, is this enough time? Thanks in advance, Paul
