This photo was taken as I was standing on the shore of the Susitna River in Talkeetna, Alaska – approximately 80 miles south of Denali (Mt. McKinley). I used my Canon EOS 6D with an 24 -105 mm Canon L lens and a polarizing filter. In the next 10 minutes or so a harsh thunderstorm struck from the west and entirely obliterated the view of Denali. Denali is the highest mountain in North America.
