I'm at the house now and found my field notebook. There are two paleosols (ancient soils/former land surfaces) that are identified in the dunes. The older paleosol is ~8000 years old. No trees have been found in it, only charcoal. The buried forest grew in the younger paleosol about 4000 years ago.
You can walk on a trail to the ancient forest. I think you have to look for a location called the "ghost forest." As you walk amongst the remains of those old trees, you are walking through a few thousand years of Michigan's glacial history, a time when the last giant beavers and wooly mammoths were seen in North America.

I love the dunes...the ones in the UP and also the ones near Traverse City. I wonder how many secrets are still hidden in them!
