Actually, I don't think Alpine Ascents, Rainier Mountaineering, or International Mountain Guides do guided ski descents of Rainier. And they pretty much only guide up the DC and ID route from what I know. Super Lame. We did the Jib to FF route in March 2008 and it was awesome. We climbed the ledges at night and had an amazing sunrise from just above Gib Rock. Hayes and I are going to try and ski the Kautz this winter. Ski these routes in the winter and you reduce your risk of falling through a thin bridge or getting stuck in a bergstrom for the rest of your life.
