| Glacial erratic wedged into tree trunk at Bald Mountain/ photos by Jonathan Schechter |
Bald Mountain State Recreation Area in northern Oakland County, Michigan
encompasses almost 5,000 acres of glacially sculpted hills and lakes.
Without much effort hikers can spot glacial erratics (boulders ripped from the Canadian
Shield and pushed south by the last great glacier some 12,000 years ago) along the trails
and in the woods.

Without much effort hikers can spot glacial erratics (boulders ripped from the Canadian

and in the woods.
Some weight just 50 pounds or so, others are tons.
But one ancient and colorful glacial erratic formed millions if not billions of years ago
before being moved and smoothed by the glacier is wedged in a tree trunk along the Graham
Lake Trail.Without question the last glacier did not put the stone on a tree.

The mystery remains: How many years ago did a human place the rock between the forked
trunk of the tree? All I know for sure is this rock is now firmly and permanently wedged
between the trunks with the expanding bark sealing it in place.
