The January thaw has created quite the stir in a Milwaukee suburb.
In Cedarburg, Wisconsin, a 4.6 metre (15 foot) wall of foam has formed on the Cedar Creek. Residents say they have seen the creek with foam on it before, but not nearly to this extent. City engineer Tom Wiza says the foam is formed upstream from a waterfall and mixes with debris from the water surface. Most of Cedar Creek is covered in ice, so the foam just keeps piling on top of it.
The foam has been tested and isn’t thought to be the result of a spill. Regardless, it is quite the spectacle!
