Leaving the Sand Dunes

You are about to leave the dunes and enter the neighboring beech-maple forest. The dunes cover just a small area because they depend on strong winds off Lake Michigan to exist. The active dune zone extends for only about a mile from the lake. Further inland, the wind loses its energy and can no longer build dunes.
