Every time I go to Denali, it snows. A lot. This was my first trip, in the first week of September 1980. A storm moved in from Siberia, and the road was closed beyond Igloo Creek. The snowy morning after it hit, I spent seven hours in hip waders standing nearly motionless in this little creek, photographing the very delicate ice patterns along both edges. Minor foot movements would wash away whole structures. The drive out was on firm snow ten inches deep. The huge, 20,321 foot mountain that dominates this park is the largest single mountain which is wholly above the sea, on Earth, both in height above its immediate surroundings (about 18,000 feet) and in volume. It makes so much of its own weather, that it is only visible from within the park on about four or five days each month, during summer. In winter, it is revealed much more often, about twenty days per month. The Mount Logan massif, in Kluane National Park in northwestern Canada, has an even greater volume, but is a cluster of peaks.
