This is also the camp where you might wake up with a headache, and where the largeness of Denali makes itself known. The bulk of the West Buttress towers above you and you can see almost to the North Summit, impossibly far away. Be sure to reacquaint yourself with your spiky friends, review your French Technique, and visualize how to dance your way efficiently up Motorcycle Hill. Rest step, anyone?
With a conservative rate of ascent, such as 1,000'-1,500' per day, most climbers don't suffer from altitude illness. But, while Acute Mountain Sickness (AMS) can present at lower elevations, 11,000' Camp is where we typically start to see it when it does show up.
Rarely do you need to cut snow blocks and build walls at 11,000' Camp. The camp is in a basin that drains to the west, so many camps are on a slope. As you dig into the slope to make tent platforms, you often end up with a wall of snow on the uphill, eastern side of your tent. This protects from winds screaming down from Windy Corner, but can lead to tents drifting in, so be prepared to shovel during a stormy night.
Be heads up, as there are often crevasses lurking under the start of the slope, and a few others occasionally present themselves higher up. Avalanches can sweep the climbing route from climber's right, and one swept a descending rope team into a crevasse years ago, with tragic results.
Skiers can generally find some great turns down Motorcycle Hill! Pay attention to where you might have suspicion of crevasses on your uphill and plan accordingly for the down.
Routes have been put up on some of the couloirs dropping down off the West Buttress, and the West Buttress Direct climbs up from Windy Corner on good granite and up steep snow.
