North Woods - Temperatures

See the difference in the temperature underground and 25 feet in the air!

On this stop on the Ridge Trail, visitors can see the difference in temperature five feet underground, three feet underground, at ground level, five feet above ground, and 25' high above the ground in the treetops. It's surprising how warm it is underground in the winter; in general, it's cooler in summer and warmer in winter as you move down from the surface. See graphs of temperatures at each of the five sensors over the course of a year - it's a clue to why many animals spend their winters underground or under the blanket of snow.
