Cloud Volcano

Well I have a short brief about this photo. Obviously I was on the plane, but I was in the window seat and I had woken to clouds like this that appeared to have mist around them. So to me I awoke looking outside the window to what looked like heaven. I took out my camera and snapped a few shots was ready to fall back asleep, but up ahead I saw this mound of clouds that looked like a volcano had erupted.
Sadly, by the time I got there this mound did shrink a bit...this mound in the middle could of been bigger. So I awaited this mound to find that the drink lady was approaching; I knew I had to take more than just one shot so I blew off the drink lady for a few seconds and got this shot as one of the three shots of the cloud volcano
