here you see a dense white cloud of something

hey there look its a close up of the white substance, water vapor?

see how much different the clouds are in the sky, this does not fit in with the other white clouds

another shot of this very different looking substance

see the other clouds in the sky on that day, they are higher up and they were not moving nearly as fast

after a matter of minutes observing, i see the white substance has moved to my left above the tree it was on the right of. this moving in a matter of minutes also provides clues that it is very low in the atmosphere

only a half minute after the last picture and the white substance has stretched out and moved even closer to the ground
