Another goodie from Banff National park. This is a view of Cascade Mountain and the small resort town of Banff at the bottom from the top of Sulfur Mountain at over 7000 ft in altitude. In april, most of the snow in the valleys is melted leaving snow covered peaks until summer. Taking pictures from high altitudes results in a blue haze when looking down below, fighting with the atmosphere, much like when looking up at the sky, it appears blue, same concept but reverse.
