Chimney Rock Park Frequently Asked Questions

Grady the Groundhog

Q: Are groundhog hides ever worn by humans?

A: Luckily for Grady, groundhog fur is not currently in vogue, partly because it is not particularly thick and warm for humans. Their hairs can be used for tying trout flies and early American Indians once used their sturdy hides for soles of moccasins.

Q: How much wood could a woodchuck chuck if a woodchuck could chuck wood?

A: Ah, this is by far the question we’re asked the most! And the answer is about 700 pounds. Compared to beavers, groundhogs/woodchucks are not adept at moving timber, although some will chew wood. A wildlife biologist once measured the inside volume of a typical woodchuck burrow and estimated that -- if wood filled the hole instead of dirt -- the industrious animal would have chucked about 700 pounds' worth. Toothpick anyone?

Q: What do groundhogs eat?

A: Well, one reason groundhogs love living in this area is because of all the succulent green plants, such as dandelion greens, clover, plantain and grasses. Admittedly they are sometimes tempted by nearby garden vegetables. They also have a tendency to binge and purposely put on weight in the summer, reaching their maximum mass in late August. Then they become more and more lazy as they prepare for hibernation in October. By February, Grady and his other hibernating buddies have lost as much as half of their body weight - perfect timing for their closeup photos on Groundhog Day!

Q: What goes on in a groundhog burrow?

A: Well, not much in the winter. You might say they take a long nap. Groundhogs go into deep hibernation, greatly reducing their metabolic rate and body temperature. They hibernate in the deepest portion of the burrow where it is below frost line. That means their body temperature can drop as low as 39-40 degrees Farenheit. Like humans, their internal clock is affected by annual changes in the amount of daylight. Hormonal responses to cyclic changes in production of melatonin, a sleep-related hormone, signal them to wake up!

Q: What's the difference between a groundhog and a woodchuck?

A: When you see a woodchuck and a groundhog, you’re really seeing the same animal. The scientific name is Marmota monax. Most closely related to squirrels, woodchucks like Grady can actually climb trees and also swim. That’s another reason they love living at the Park – lots of places to swim and climb.
