Full Worm - March Moon
As the temperature begins to warm
and the ground begins to thaw, earthworm casts appear,
heralding the return of the robins. The more northern
tribes knew this Moon as the Full Crow Moon, when the
cawing of crows signaled the end of winter; or the Full
Crust Moon, because the snow cover becomes crusted from
thawing by day and freezing at night. The Full Sap Moon,
marking the time of tapping maple trees, is another
variation. To the settlers, it was also known as the
Lenten Moon, and was considered to be the last full
Moon of winter.
