2018 Field Trips

GSM Tours and Fields Trips in 2018


The following field trips and tours are planned by the Geological Society of Minnesota for 2018. This page will be updated with dates and other specifics as each event is scheduled. GSM members will also receive e-mail notices. If you have particular interest in one of these trips, consider helping with the planning and organizing; contact Dave Wilhelm at .

A field trip to Isle Royale National Park during June 18 through 24, 2018, led by Erika Vye, Bill Rose, and Stephen Roblee. These are the same persons who led us on the superb Keweenaw Peninsula trip during July, 2015. This trip will leave on the Ranger III from Houghton, MI, spend 3 full days on Isle Royale, returning on the Ranger III on the fifth day. The sixth day will be an overview of Keweenaw geology. While on Isle Royale, the Michigan Tech research vessel Agassiz will take us to many scenic and geologically interesting sites, allowing us to see the beauty and geology of Isle Royale from both land and water. We have started actively planning this trip; members are being notified by e-mail as details develop. As this trip is limited to 17 persons, persons who were members prior to January 1, 2018 will have priority, and sign-up will be on a first-come, first-served basis by e-mail in February. Eight GSM members participated in a similar trip during June, 2017, and had an excellent time. Until an online description of the 2018 trip is available, please look at the description of the 2017 trip here, as 2018 should be similar. Photos from the 2017 trip are here. Look for Dave Wilhelm’s report of the 2017 trip in the August, 2017 GSM Newsletter.


A field trip in the Thunder Bay, Ontario area during Summer, 2018, led by members of the Ontario Geological Survey. OGS personnel are very eager to show us the highlights of geology in that area, and there is quite a bit to see. We will start actively planning this trip in February; members will be notified by e-mail. Most likely time is latter part of July, and most likely duration is 2.5 to 3.5 days.

One or more 90-minute walking tours of the building stones and architecture of downtown St. Paul, using the book “Rocky Roots” as the primary source book.  We will not cover all of St. Paul, but a short 1½-mile course from the Science Museum of Minnesota to Rice Park, Landmark Center and several other interesting buildings along St. Peter Street and Wabasha.  In this, we will discuss the geology of the building stones, architecture of the buildings and history of St. Paul and the State of Minnesota.  We will show many interesting features found in rocks and discuss how these are formed in geology.  Highlights will include some of the most spectacular examples of the Morton Gneiss, cleanly cut and polished.  We will see examples of the products from the Twin Cities Brick Company that went into many of the buildings in St. Paul.  The old “Brickyard”, now Lilydale Regional Park, was the site of several GSM fossil hunting field trips in the past.

GSM plans to continue arranging one or more weekday tours to St. Anthony Falls Laboratory each semester as member interest dictates, so you will be notified of other possible opportunities as they arise. Look for Deborah Naffziger’s report of two 2017 tours of SAFL in the May, 2017 and February, 2018 Newsletters.
