When MDOT and OCRC was working on the intersection of Adams Road and M-59, they made a discovery - mastodon bones. There is a marker a bit south of the parking area on the trail. The remains of the mastodon were moved to two places, one a nearby at Cranbrook.

For information on the trail itself, since it has it's own website and Facebook, I won't duplicate information other than this trail comes highly recommended.
