Here is a brief report of an attempt on Denali made during May 1995. Our expedition consisted of 2 members - myself and a friend from Cambridge, England. It is a little over 20 kft tall and has a reputation for some rather nasty weather.
Most climbers attempt the West Buttress route.
They incur significant additional avalanche and cravasse danger however because of the need to traverse the full length of the dangerous Kahiltna NE fork. Few mountains have as many books written to aid the climber as Denali. These books contain just about everything you could wish for short of very detailed technical route descriptions. What happened First we flew to Anchorage then the next day took overland transportation to Talkeetna. There was a couple of days wait here for weather good enough to fly.
