Field Trip Report

GSM Tours and Fields Trips in 2017

Field trip summaries back to 2011 now on the web site.

2017 Field trip info on the GSM web site as of 08-FEB-2017:

The following field trips and tours were offered by the Geological Society of Minnesota in 2017:

On Saturday afternoon, January 28, Dave Wilhelm organized a 2+ hour tour of the Wildlife Science Center in Columbus, MN. About 40 GSM members and guests participated, including some young children. The temperature hovered around 25 degrees, so the animals were fairly active to maintain body heat. The tour started with an indoor presentation about WSC and its inhabitants, followed by an outdoor tour to observe the animals up close. We saw, heard (and smelled) gray & red wolves, coyotes, foxes, a mountain lion, bobcat, porcupine, and screech owl, and got detailed explanations of their behaviors and interactions (great photos here). And we were exhilarated by choruses of wolf howls a few times during our visit. The current address of WSC is 5463 W Broadway Ave, Columbus, MN, near Carlos Avery Wildlife Area. This is about 31 miles (35 minutes) north of downtown St. Paul. The Center will be moving in March, so our event was one of the last opportunities to tour the present site. Photos from this tour are here.

The following tour is planned by the Geological Society of Minnesota in 2017:

On Saturday, 11 Feb 2017 from 10 AM until 12 noon, we will be given a tour of the American Engineering Testing Company in at 550 Cleveland Avenue North in St. Paul by Dan Vruno and Chris Tillema of AET.  AET specializes in petrography (study of detailed descriptions of rocks) and making and testing cement. Among other projects, AET has been involved with the new St. Croix River Bridge (subject of Dec. 5 GSM lecture) and the Green Line Light Rail. If you have not already signed up for the tour, send e-mail to Steve Erickson at

The following field trips and tours are tentatively planned by the Geological Society of Minnesota for 2017. This page will be updated with dates and other specifics as each event is scheduled. GSM members will also receive e-mail notices. Some of these events are just ideas at this time; we do not expect that all will actually happen in 2017. If you have particular interest in one of these trips, consider helping with the planning and organizing; contact Dave Wilhelm at .

Starting in winter 2017, GSM plans to arrange one or more weekday tours to the St. Anthony Falls Laboratory each semester as member interest dictates.


Randy Strobel will lead the following three separate field trips this summer:

-          Walking trip of Minnehaha Falls and the nearby Mississippi River gorge,

-          Walking trip of the Minneapolis riverfront at the Stone Arch Bridge, including a visit to Mill City Museum; and

-          A biking trip on both sides of the Mississippi River Gorge from Lock & Dam # 1 to up to the Stone Arch Bridge and back.

These are areas that Randy described in his February 6 lecture to GSM. As dates and other details are determined, we will make them available by e-mail and web site.

A visit to Eagle Lake Observatory, hosted by the Minnesota Astronomical Society. The primary purpose of this visit would be to view Saturn as its rings are oriented to nearly their best viewing angle from Earth, but of course we would also observe other astronomical bodies. See photos from our 2016 visit to this observatory here.


There will be a total solar eclipse across the United States on Monday, August 21, 2017. Here are web sites that track its path:

GSM is planning a field trip whose primary purpose will be to view the eclipse. But since we will head many hundreds of miles south or southwest, we might as well include some geology and make a week of it. A likely destination is southern Missouri, with the Ozarks, and southern Illinois, which also has some beautiful landscapes. These are within easy car driving distance from Minnesota, with a Saturday departure. Further away would be Colorado, which of course has lots of geology and scenery. Idaho and Oregon are also possibilities, but then you’d either need to fly, or spend much longer driving there. Recently, I asked members for their interest in such a field trip. So far, over 40 persons have expressed significant interest in such a trip, so we will continue planning. If you are interested and have not yet responded, do so as soon as possible to Dave Wilhelm at, as further e-mails on this trip will be sent only to those who have indicated interest.

A trip to Theodore Roosevelt National Park in September 2017, in conjunction with an astronomy trip being planned by Minnesota Astronomical Society.

A half-week trip to museums in Chicago, including the Field Museum and the Museum of Science and Industry. We might also include a stop at Indiana Dunes National Lakeshore.

Do-it-yourself Geology Field Trips in Minnesota

Submitted by Rebecca Galkiewicz


Minnesota has a lot to offer when it comes to scenery and geology.  The GSM is not a tourist bureau, but has helped tourists and citizens understand the geologic wonders.  How?  By erecting 60 geological markers around the state.


The next time you take a trip to the North Shore, along the Minnesota River, the Metro Area, or anywhere else in the state, consider visiting several geology markers along the way, using “Do-it-yourself Geology Field Trips”.  


Here is a list of twelve suggested “Do-it-yourself Geology Field Trips”, covering the entire state.

  • Northwest Corner
  • Brainerd-Lake Mille Lacs
  • Alexandria and Big Stone
  • Minnesota River Valley
  • Southwest Corner
  • Karst Country (Southeast Corner)
  • Mississippi River Valley (from Hastings south)
  • St. Croix River Valley
  • Metro Area
  • North Shore
  • Route 35 North
  • Iron Range


GSM members can provide a helpful service by reporting any marker vandalism and GPS coordinates to the GSM Marker Committee.  We plan to make these DIY Geology Field Trips available to the general public through our website.







GSM Questions Report


GSM Question listing update: 7/29/2016-1/2017

Keep in mind that this list is comprised of the questions that the GSM website had received thus far, and that it does not contain all of the correspondences pertaining to each of the questions.

  1. Classroom Presentation -  (Theresa Tweet – wanted class presentation during December 12-20, Finals week. Lindsay said to keep her in mind for next year.)  
  2. Classroom presentation – (Theresa Tweet, - Michael Murphy did the presentations).
  3. Rock Identification -  (Theresa Tweet – invited Todd to a GSM Lecture - perhaps someone there could identify it. Also, sent the Rock Shop link as another option. ) 
  4. Agate Advice -   (Val   – After forwarding the pictures that were sent, Val answered and said that it was, for lack of a better word, a large piece of jasper.)  
  5. Attending Lectures -  (Theresa Tweet – we no longer go by the time posted on the inner lecture hall clock, instead we use cell-phone time. Actually, we have just been standing out by the door for 15 minutes so that we don’t miss anyone.
  6. Winner @ Swedish GSM Fall Conference  (Theresa Tweet – what? Mistakenly sent email to the wrong address).
  7. Fossil Identification -  10/14/2016:  (Theresa Tweet – even     with photos, the fossils were difficult to identify.
  8. Fossil Identification -  9/22/2016: (Theresa Tweet             – because Shannon asked about fossils, I asked for pictures – none were given.)
  9. Object ID Program / Science Museum – 9/16/2016:  (Theresa Tweet – removal of the Science Museum’s Identification from our webpage.)

  12. Stone Tool Identification – - 8/21/2016:  , (Theresa Tweet recommended our webpage  in hopes that a local rock shop would be able to help with the identification.)
  13. Formation found while digging – 8/14/2016:  (Dave , asked for pictures, but when they were received, it was too difficult to say what the formation was).
  14. USGS Map Folios to give away – 8/11/2016: , (Theresa Tweet – wrote back many times, so I am guessing that they are no longer available).
  15. Presenter to compliment FOSS – 8/10/2016: . (Theresa Tweet – the Outreach program was not up and running yet for the year, so we were unable to fill this request).
