This is Dave Hahn checking in from the familiar surroundings of Advance Base Camp at 14,000'. Life is good here, but we're not so sure that's the case at 17,000'. A cloud cap formed over the summit of Denali this morning, indicating high wind and changing weather conditions. Sometimes a cap will blow off, followed by settled weather. On the other hand, it may be a harbinger of worsening weather. At any rate, we're sitting tight for the moment, watching and waiting. We'll keep you posted.
