In July 2014, we led geotours on two full days each on three of the five Geoelements of Keweenaw Geoheritage.  These tours used ground and boat transportation and visited some of the most important places identified by the website.  We used the university research boat, the RV Agassiz. The three trips are described below. We expect to post a plan for 2015 soon. Registration and cost information for these trips is available through the Western Upper Peninsula Center for Science, Math and Environmental Education. Each trip is limited by the boat capacity to 17 people.GeoElements.html

Keweenaw Geoheritage Field/Boat Trips--
July 21-26, 2014

July 21-22 Lavas and the Keweenaw Rift    Details
This trip is to see and understand the Keweenaw’s black rocks and its deep earth volcanism past. It is the site of Earth largest lava outpourings. Magma oceans existed here. We will see the huge lava flows and how they shape and influence the peninsula.
Highlights of the trip include: The Great lava reefs and shipwrecks of the Eagle Harbor to Copper Harbor shore, The Greenstone Flow (Earth’s Largest) and its anatomy, Copper and lavas--how do they relate? Manitou Island and the Lake Shore Traps, Bare Bluff and Keweenaw Rhyolite.

July 23-24 Keweenaw Fault    Details
This trip is to see and 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, the Quincy Mine and the Pilgrim River Valley.

July 25-26 Jacobsville Sandstone    Details
This trip is to see and understand the red rocks that were carried by rivers from the Huron Mountains (which were huge then) into the great valley of the Keweenaw rift. The best way is via the lake, where we will visit Pt Isabelle, Point Louis, Rabbit Island, Traverse Bays, Rabbit Bay and Jacobsville/Lower Entry. We will see the important fossils of the redbeds at Horseshoe Harbor and the Nonesuch Shale at the Gratiot River Mouth.
