The beaver moon is the first full moon in the month of November. The time of the Beaver Moon was the time for both the colonists and the Algonquin tribes to set beaver traps to ensure a supply of warm winter furs. This full moon is also known as the Frost Moon because it's about the time of the first frosts.
The farmer's almanac included nicknames for the full moon depending on what month they occured. Most of these nicknames were based on the names North American aboriginal people used. Although many tribes gave nicknames to the full moon, the most well known come from the Algonquin tribes who lived in the area of New England and westward to Lake Superior.
