This was the time to set beaver traps before the swamps froze, to ensure a supply of warm winter furs. Another interpretation suggests that the name Full Beaver Moon comes from the fact that the beavers are now actively preparing for winter.
It is sometimes also referred to as the Frosty Moon and as this is also the next full moon after the Harvest Moon, it can also be referred to as the Hunters' Moon. With the leaves falling and the deer fattened, it is time to hunt. Since the fields have been reaped, hunters can ride over the stubble, and can more easily see the fox, also other animals, which have come out to glean and can be caught for a thanksgiving banquet after the harvest.
