Greenstone Ridge Trail

The island is within Isle Royale National Park.

There are no roads on the island, a wilderness area and national park, so the trail doubles as the primary means of land transportation across the island.

Hikers may see signs of the wolves and moose on Isle Royale; although scarce and shy, the woodlands that adjoin the trail are their habitat.

[2] The Greenstone Ridge and its Trail are both named after Chlorastrolite (Greenstone), a local semiprecious stone that is the state gem of the U.S. state of Michigan.

Greenstone can be seen in various locations on Isle Royale, including shoreline pebbles.
