Ground hogs are good diggers. They make burrows for sleeping, rearing young and hibernating. These burrows have multiple entrances that they can use them to escape predators.
Groundhogs are mostly diurnal but our Elms groundhogs are often out of sight when the students arrive to Elms and they come out when all is quiet again.
