Phenology

Fourth Week of February

Sap from sugar maples and other tree species usually begins to rise in late February. European explorers were astonished that Native Americans used maple sap for sugar, who likely figured out its value by observing squirrels that licked sap from broken sugar maple twigs and branches. Native Americans obtained sugar much the way it is done today, by cutting small holes in maples, inserting wooden tubes, catching the sap in birchbark buckets, and boiling it down. Americans consumed more maple syrup and sugar than any other sweetener, like honey or cane sugar, until around 1875. White-tailed deer have begun shedding winter fur. In northeast Minnesota, black bear cubs are now about a month old, weigh less than three pounds each, and are in dens with their still-sleeping mothers.
