冬天在北半球攀登的定义是12/21-3/21 (但是喜马拉雅地区的定义是12/21-2/15)。所以mark twight 的Mt. Bradley确实是冬攀,但是当时天气非常温和,多在-21度以上。他的hunter之行不算,因为是五月爬的(5/15-5/17, 1994)。不过他们爬这种路线基本不睡的,坐在那里烧水,顶多歇1-2小时,所以不要和大众的冬天野营混淆。以免误导。
天气情况的描述在此:http://classic.mountainzone.com/climbing/twight/alaska.html
"Taking advantage of weather patterns allegedly caused by El Niño, and assurances by Park Ranger Darryl Miller that the winter in the Alaska Range had been "extremely mild", Jonny Blitz, Steve House and I flew on to the Ruth Glacier on February 28th, 1998. The first few nights at our 4400' base camp were quite cold, -25° to -30°F, but temperatures moderated thereafter, probably never dipping below -5°F for the next 10 days. The camp received approximately 10 hours of daylight, increasing by seven minutes per day, and just five hours of sunlight, as the sun rose from behind the Hut Tower and disappeared behind Mount Wake."
