I had not seen that, but...I am not in the least surprised.
It is easy to understand why humans view beavers (the animals) as nearly autistically industrious...because they ARE!
Those are some hard working critters. Hell, even the people who worked on the Hoover Dam just had to put down their tools sometimes!
I first saw that on one of my favorite TV shows called “What On Earth?” where they investigate strange, anomalous images that pop up on satellite photos.
They had to actually fly part of the way and then pack in, to see what it really was.
It is *huge*.
[and part of me giggled at the thought of your liberal neighbors having *that* pop up in their world]
