Regulator going up Chulitna Hill - McKinley in the background: This photo was taken on the same regulator trip as last week's photo (note the red flags are still in almost the same position) and was only a few days apart. Needless to say that the weather can change quickly from cold and windy to a beautiful sunny day like this photo where "The Mountain" is out in all its glory and one can't help but feel fortunate to witness such days.
