  Lovely shot Len!
  Never seen those, except for in movies, when Enterprise engages warp drive!
  Cool, compelling and wondrous!

  That's an incredible cloud formation, Len. And you even got a great foreground to go with it.

  Thanks guys. These clouds are formed by large jets passing through lower level strata. The air rushing over the wings of the planes causes the air to rapidly cool and expand. The result is ice and snow. This image was take from our house....about 60 miles from the San Francisco & Oakland airports......just about where many of these planes begin their decent from crusing altitude.

  When I first saw one of these, I just had to find out how and why?

  This also brings to mind the movie "The Day After Tomorrow" when they had the storms that ended up going into another ice age.

  Great shot, never seen that before! I saw an almost perfect square hole of blue sky in a grey sky though once! Wonder what caused that?
