March's full moon has many names! The Farmer's Almanac was a wealth of information :)
Other names: Full Crust Moon; the snow thaws by day, freezes by night forming a crust. Full Sap Moon. Quick! Time to tap the maple trees. I so fondly remember the pancake breakfast at Cuming Nature Center in western NY. They made great maple syrup there.
Early settlers called it a Lenten Moon, the last full moon of winter.
