As the chill air of late fog descends, animals begin to prepare their dens for the deep freeze of winter.
Beavers can be seen along the banks of rivers and streams, collecting wood to shore up their lodges and dams before the ice sets in. This was also the time Native American tribes and later European settlers set beaver traps to ensure a supply of warm furs for winter.
Thus November’s full Moon is most commonly known as the Beaver Moon, in honor of these industrious semi-aquatic rodents.
Because November also signals the time when bitter hard frost’s become more frequent, this month’s Moon is also sometimes called the Frost Moon.
