Created by generations and discovered by satellite, now 2790 feet long in Northern Alberta, Canada.

How many beavers per acre and how many calories do they spend on maintenance instead of on rearing children? And are the beavers a product of the dam, existing because they made it? Are later generations of beavers more collectivist than earlier ones? And if it fails after several more generations, will that tell us something about the future of New York City?

Forgive my foolishness…

Always the engineer, I think that the dam building is a large part of child rearing; they need a stable water level to keep the entry to their lodge underwater (lest they and theirs be eaten) while keeping the dome of their lodge above water (lest they and theirs drown). That's why they hate the sound of running water and will throw all amounts of sticks at the loudest babble.
