How did this recent warm March impact maple sap harvesting?
Tapping maple trees usually occurs in late winter and early spring. In Wisconsin, March is a prime month for tapping sugar maple trees and this is when the sap is sweetest. But, only about 2 percent of the sap is sugar, so it has to be boiled down to remove the water and increase the sugar concentration. Continue reading

How do large snowflakes form?
There are four basic shapes of ice crystals: the hexagonal plate, the needle, the column and the dendrite. The dendrites are hexagonal with elongated branches, or fingers, of ice; they most closely resemble what we think of as snowflakes. The temperature at which the crystal grows determines the particular shape. A snowflake is an individual ice crystal or an aggregate of ice crystals. Large snowflakes are aggregates of ice crystals.
