Frozen monongahela river February 2015.

This is a 4 hour time lapse of the frozen monongahela river to see if the ice moves in the barge trails. As I see it nothing happens except when a barge does go thru then afterwards it stops again.
you can watch the clock on the opposite side of the river that and the clouds are the only thing interesting.
I may try to re-crop to have more of the sky showing...
