Ice jam

Ice Video

This video illustrates a natural source of jamming:  ice flow on Mimico Creek.  Due to different breaking rates, the ice is seen to build up in a stationary jam, and then return to flowing downstream.  Like we discussed in class, it it likely that bottlenecks (in the form of a narrowing stream, fallen logs, unmelted ice, and other obstacles) played a role in this behavior.  While ice does not display the same sorts of inhibitions that people do (slowing down to avoid collision, etc), varying currents in the stream probably play a role in seemingly "random" build ups.
