The Snow Report
Summiting Rainier is a challenge any time of year. Making the climb in winter, when unpredictable snow storms and high winds hit the mountain, is substantially tougher. The National Park Service recommends that only experienced mountaineers who know their way around avalanche country attempt a winter ascent. The maximum winter group size is 12, and the NPS recommends a minimum of four climbers.
International Mountain Guides offers a seven-day guided winter ascent for $1,850.
