Here is a scientific riddle... héhéhé!
Today I went on the field to see how the Eagle Creek looked like in January....
I drove on the 56th street which cut the reservoir on the middle... and I've been surprised to see that the northen part of the reservoir was full of ice and snow and the southern part didn't have almost any...
Why?
Here is the northern part:
plus... a little track under the snow... ;-)
Do you have any idea?
