Keweenaw Fault   
This trip is to see some highlights and to begin to understand the Keweenaw Fault, a massive thrust fault which was the locus of hundreds of high magnitude earthquakes and which split the peninsula lengthwise and uplifted rocks, including copper, to a place where people could find it.
We will visit the Fault along the Keweenaw shore at Keweenaw Point and Bete Grise and then Mt Bohemia, Gratiot Lake, Trap Rock Valley, the Natural Wall, Hungarian Falls, and the Pilgrim River Valley. Click on Green words below for more content.

The tour will be done in two groups, to accomodate the large size on the Agassiz.  The schedule listed below is only for the first group.  The second group will visit the same places, but in different order.

9:00 am: meet at Haven Falls.
10:00 -1230 am: Board Agassiz at Lac la Belle Marina, visit High Rock Bay and Keystone Bay (Mesquite Wreck), return past Fish Cove and Mt Houghton to Bete Grise.   Continue to Bete Grise Landing. 
12:30 pm: Lunch at Bete Grise Beach. 
1:30-4:15 pm Drive/Walk to Bare Bluff overlook.
4:15 pm: To Lake Gratiot area. Drive to Old Colony Road, and walk to Natural Wall Ravine (0.1 miles in forest--feet may get wet!)
5:30 pm: Hungarian Falls and the Fault. (Walk 0.4 miles, easy but possible wet feet!)
6:30 pm Hapapuura Rd and Pilgrim River fault sites

















What to bring:  Several layers for wind and cold conditions, possible rain? But it could be warm also! Strong sneakers or light hikers for shoes. Camera! Good spirits.
