'Busy as a beaver' is not an expression you hear often these days. Perhaps it is just as well.
Actually I am not sure I've ever seen evidence of beaver-work as much as I did recently.
There wasn't just a dam -- there was a system of dams.
I never would have believed such a thing was possible in the modern age. Surely, by now, beavers have learned to just sit in cubicles and dick around all day on the computer, optimizing dam design; while the actual physical construction of the dams is outsourced to a construction crew of Mexican beavers.
Perhaps every now and then, the American beavers get involved in "field work." And here is the result.
The photo plays it down, but water was pouring over from the pond onto the forest road. The road was actually eroding. My bike was slopped up with mud.
Moral of the story: this is what happens when there is an over-reliance on computer models in engineering work.
