How Do Beavers Build Their Dams?
from The Quiet Shift: Everyday Wonders for Sleep Hosted by The Quiet Shift
In northern Alberta there is a dam 850 metres long — twice the Hoover Dam — visible from space. It was built by beavers. Tonight: the animal that fells trees in twenty minutes, digs canals to float lumber home, and builds at the sound of running water by pure instinct. How a pond becomes a moat, a lodge becomes a fortress, and a winter pantry hides under the ice. Plus: the beaver pelt as currency, the near-extinction and comeback, the 76 beavers parachuted into Idaho in 1948, and the wildfire that stopped at a beaver wetland. Just long enough to fall asleep to. 🌙
