Geology Department N e w s l e t t e r

Greetings! It has been a year of change in the Geology Department. Our long-time chairperson and friend to all Dr. Peter Calengas retired on June 30th. Soon after, we learned that our wonderful secretary Diane Edwards was retiring. Then, at the end of November, our Museum Curator and all-around do everything person Bob Johnson was let go by WIU as part of their budget cutting efforts instituted last academic year. Despite all of the personnel changes, the Geology program has sol- diered on. Our Acting Chair of Geology, Dr. Samuel Thompson, is very supportive of all of the activities that we have done over the years (ex. field trips, Bonding Night, Holiday Party, undergraduate research) so we continue to provide our Geology majors the same undergraduate experience that students received during better economic times for the State of Illinois. We post photos from many of our events on our Facebook page so please check it out if you haven’t already done so.

Of course, we can’t thank our alumni enough for their generous financial support. Without the funds we receive from alumni donations we would not be able to offer our students scholarships and financial support for undergraduate research projects. We also appreciate the willingness of many of our alumni to visit the department and speak to our current Geology students. Seeing the variety of jobs that our alumni have taken helps assure our students that they can have a successful and fulfilling career after graduation from our program. We are always looking for alumni to return to the department as guest speakers or just to drop by and say hello.

I hope you enjoy reading the newsletter. Please keep in touch, I love to hear from our alumni. Steve Bennett Alumni Newsletter Editor

2016 was a quiet teaching year for me. Teaching included my usual Oceanography, both semesters, a section of Geology 110 for honors students in Spring semester, and Seds in Fall semester (to a more normal six students after the huge class last year). Summer was more interesting with the largest field camp class I’ve ever taught: 22 students. Since there were so many students, Dr. Tom Hegna came out as well to assist. A good time was had by all, but I worked harder than ever—that is a lot of students! We also made sure that both Tom and I learned the second part of field camp, that taught by Dr. Kyle Mayborn, just in case one of us needs to teach it in the future (back-ups are always good!).

If classes were quiet, undergraduate research was anything but quiet! I had Horseback riding with some of the a total of five students working with me in 2016. Three of them (Justin field camp students in South Dakota Christensen, Andrew Kerin, and Nick Liming) worked on different aspects of cave pearls from the Quincy underground limestone mine. Nick and Justin presented a paper at the North-Central GSA Meeting in Urbana-Champaign in April and I presented a slightly larger version at the national GSA meeting in Denver. We are really getting close to completing that project—look for a publication soon! In addition, Angela Elzer sacrificed some spare time in field camp to measure the carbonate portion of the Deadwood Formation in Little Elk Creek canyon (right where field camp starts on the first map). Then, in the fall, she worked up the petrology and figured out the depositional environment. Finally, Allison Hartman started an Honors Thesis working on pool fingers from Blauhöhle Cave, Germany. We went out to Albuquerque twice to use the SEM at the University of New Mexico and now she has to write up the results.

On the personal front, I managed two trips out to Seattle to visit family. If you ever get the chance, the Washington coast is just about the prettiest place on the planet (or least high on the list!). I also continued my woodworking, this year completely replacing the front porch on Kyle Mayborn’s house—a project that just kept going and going and going! Mari Mayborn did all the design, and I built it. Six months after starting, I have to say the final result came out rather nice! I also got in lots of horseback riding (no falling off this year!) and spent way too much time taking cute pictures of my two new Maine Coon cats.

Thankfully, 2016 was a calmer year than 2015. I again took the Paleontology students on a trip to Iowa City to see the paleontology collections at the University of Iowa, the Field camp selfie MAPS fossil show, and the Fossil Gorge. Shortly after that, I attended the North Central meeting of the Geological Society of America in Champaign, IL. I chaired a session there, gave a presentation, and brought several students who presented their research.

During the summer, I helped Leslie Melim teach the first four weeks of Field Camp in the Black Hills of South Dakota. When I was a student at the University of Iowa, we mapped in some of the same areas, so it was neat to see them again. This year we had our biggest group of students for Field Camp ever—despite that, they were a great group to have out in the field! Aside from that trip, I did not have any other major trips during the summer, so I got to spend the rest of the summer in Macomb with my family, writing up research papers. One of the projects that I finished up this summer has been published and is receiving some press attention: http://www.earthtouchnews.com/ discoveries/fossils/wow-fossilised--eggs. Also during the summer, the research paper resulting from former research student Hunter Starr’s undergraduate research project was published.

In the fall, my teaching load changed slightly. I will no longer be co-teaching the Integrated Science I class for our teacher education students. Instead, this fall, I taught a geology field trip class that I called ‘Ordovician North, Ordovician South’ where we traced the expression of the Ordovician Maquoketa Formation from northern Iowa to Missouri, and looked at related formations along the way. A good time was had by all. Also in the fall, I attended the National Geological Society of America meeting in Denver, CO. There, I gave a talk entitled “The amber window and the amphipod fossil record.”

Over winter break, I submitted round 3 of our Scanning Electron Microscope grant—with positive reviews last year, we’re again hoping this is the year it will be funded. We have a number of faculty from WIU involved in the grant, and if funded, it will significantly enrich our classes and student research projects to have a piece of equipment like that on campus for easy access.

My adventure in the Dean’s Office as an Interim Associate Dean has continued into this year. I experienced a steep learning curve during a very difficult time for the University. Overall, the work has been challenging and interesting, but I am thankful that my day still starts in the Geology Department where I continued to teach Mineralogy and Igneous/ Metamorphic Petrology. Last spring for Petrology we went to southeast Missouri for our annual field trip, which included a mapping exercise along the St Francis River near the Silver Mines Campground. Drew Laviada-Garmon at Washington University On the research front, I managed to keep working with Microprobe Facility. Thank you to contributors to undergraduate students on the Mineral Lake Intrusion. the Geology Foundation! Two students and I took a series of closely spaced samples along the contact that Luke Smith and I studied a year ago. We are attempting to make a detailed map of a marginal reversal located at the base of the intrusion and then to use the map and geochemical data to determine the origin of the reversal.

On a personal note, Mari and I visited Yosemite this past January during our annual trip to see family in California. I have visited Yosemite a few times in the past, but this was my first visit during the winter. It was fun to hike with Mari, to take an early morning run along the trail up to Yosemite Falls and to stand at the base of El Capitan at the start of the famous “Nose” climbing route. I also enjoyed walking through “Camp 4”, the birthplace of modern rock climbing, Black Diamond climbing gear, and the Patagonia clothing company.

Thanks to everyone who has kept in contact. I really enjoy seeing you progress in your careers and appreciate when you notify us of entry level positions for our current graduates. Please send me an invitation on LinkedIn, if we are not already connected.

All the best, Dr. Mayborn

We had beautiful weather for our annual spring picnic, which we once again held at WIU’s Horn Lodge. Even the canine attending the event seemed to have a good time!

I cannot believe that I must report that I did nothing in the way of geology trips or park visits this past year. What a sad existence. Luckily for you, I am going to report on my four cats. Report card A+. Pets bring joy to life as well as hairballs on your bed, carpet, couch or wherever. Cats are great collectors of mice, live or dead, doesn’t matter. Pets are also very good at sharing, especially their fur. They will happily coat everything you own in fur, free of charge. Very kind of them. (Note to self, no white-furred pets ever again.)

Secondarily, my oldest son is now attending Illinois State University studying diligently his strategies on how to win Warhammer 40K tabletop games. When he is not otherwise occupied playing Warhammer 40K, D&D, Pathfinder, Magic the Gathering or any other myriad of games, he is studying Physics and Japanese. He is quite enjoying a parent-free life.

Thirdly, my youngest son is a junior in high school and can be found ensconced in his room playing his Xbox or PS4 almost anytime of the day or night. Much to his detriment, he trained one of the cats to take over the controller when he has to make a pit stop for more munchies. Cheerio Puff (a great ball of white fluff) changed his user tag to “My Cat is Cheerio Puff with her WAY Better than your Mangy Dog”. Needless to say, next time he played Call of Duty on- game-face on line, the dog owners kept taking him out until he figured out what was going on and fixed his user tag. He now carefully monitors the cat’s use of his head set and controls, or so he thinks. Little does he know the kind of mischief she gets into when he is away at school. She has become adept at plying the controller with all four of her little paws at once and has quite a following on YouTube.

My life is not as fascinating as a cat’s. They have it easy. Eat, sleep, barf, eat some more. What more could you ask for? Hope you all have a good year. Geology rocks! (Pun intended.)

I am extending my sincere greetings to the friends and alumni of the Department of Geology. I am chair of the Department of Geography and interim chair of the Department of Geology. Why am I taking on two chairships? Well, with Dr. Pete Calengas’ retirement in June 2016, a decision was made not to replace him. The department was left without a chair, and I was asked to serve as the interim chair of Geology, in addition to my other chair duties. I accepted the challenge because the Geology faculty are my neighbors in Tillman Hall, and I want to help out in times of unusual budgetary circumstances. The Geology faculty and students have been supportive, and I look forward to completing a successful academic year in the department. No one knows what changes may occur next year, but right now I am serving as the interim chair through June 30, 2017.

As of January 2017, we are making do without the service of Bob Johnson. He was laid off effective December 31, 2016. Fortunately, Dr. Thomas Hegna has stepped in as director and curator of the Geology Museum. Now the museum door is open on a daily basis.

I want to thank you for your donations to the department. I have seen at first-hand how your donations are supporting academic programs and other important activities in the department. The programs and activities could not have been possible without the funds in the department’s foundation account. Your generosity is highly commended. Thank you for all the good things you do for the department.

My name is Cerese Wright, and I enjoy rock wall climbing, deep sea diving and running marathons. Can you believe it? Actually… I don’t do any of that; I just needed an attention grabber. Let me introduce myself as the new Office Support Specialist for the Geography and Geology Dept. I am amazed how interesting these departments are. From the fascinating Geology museum, to Geography, to the GIS Center -- there is always something going on. I am happy to be a member of the team and get to work with the very talented faculty members we have here. My name is pronounced (sir-reese). There are many different spellings. The dictionary describes it as a deep to vivid reddish pink color (spelled cerise). I was fascinated to also learn from a former WIU faculty member, Tom Van Heuklon, that there is an asteroid named Ceres. It is the largest object in the asteroid belt that lies between the orbits of Mars and Jupiter. Its diameter is approximately 945 kilometers, making it the largest of the minor planets within the orbit of Neptune. With her four daughters I enjoyed meeting & talking to students of the Geology Club at the Holiday party in December. There was lots of food, an awesome game, and some interesting conversation. A great time was had by all at the Old Bailey House. I’m now looking forward to the spring picnic that I have heard so much about. On a personal note, my husband Tom and I spent most of 2016 helping our daughter, Melissa and her fiancée, K.C., get ready for their August 2016 wedding. Our other daughters Melanie, Marlena & Meghann all took part in it. It was held in East Peoria with the reception at the Stoney Creek Inn located on the scenic banks Earth, Moon, of the Illinois River. If you have never been to that Lodge, I think it would really and Ceres appeal to you if you like the outdoors. Each room was decorated in a different theme such as: moose room, fishing room, bear room, etc. We especially enjoyed the large fireplace in the lobby, too. It all made you feel like you were deep in the woods. It was a beautiful occasion, and we made lots of memories. I look forward to hearing about all the Geology Department’s adventures for Stoney Creek Inn 2017. Stop in and say “hello”.

The last year has brought a lot of changes. The Geology Department had some retirements, my house is a bit emptier with my son Nathan off at college (Illinois State University), and we had an addition put on our house over the summer. However, all of my stress melts away when I’m teaching my courses to our wonderful students. I continue to teach Introduction to the Earth, Geologic Field Methods, Hydrogeology, and Energy and Earth Resources (online). For the Fall 2016 semester I also took over Dr. Calengas’ Environmental Geology online course. Although I enjoyed teaching the course, I’ve passed the course on to Tom Hegna so I won’t be so overloaded. I’m still Treasurer for the Illinois Groundwater Association so, if any of you are working in the environmental area, I would be happy to get you involved with After helping my son buy this organization. We are always looking for new members! We will be holding textbooks I can truly our first joint meeting with the Illinois Association of Groundwater Professionals, commiserate with the sticker which is comprised primarily of well drillers and contractors. It should be an shock my students interesting mix of people since our membership consists of academics, experience! graduate students, state workers, and environmental consultants.

I continue to advise undergraduate research projects in the Spring Lake watershed. One student finished her project on nutrient concentrations and another is continuing research he began last spring using the U.S. Army Corp or Engineers HEC- HMS software to model hydrographs. My own research involves estimation of abandoned and/or undocumented wells in McDonough County. Speaking of abandoned wells, last summer the local groundwater education group I chair (McDonough County Groundwater Protection Education Committee) sealed an abandoned well to educate people on their dangers. Although we have done these in the past, this demonstration was new to us as it was not a rural well but was in Macomb (south MacArthur Street) right next to the homeowner’s back door. I felt particularly good about this well sealing because the homeowners are both faculty at WIU. One of them approached me after hearing a presentation I gave on protecting groundwater and I told her we may be able to seal it for her. I mentioned the well to Steve Wilson (Illinois State Water Survey) who developed and runs the online Private Well Class (http://privatewellclass.org/) designed for homeowners with wells. Long story short, he paid for the well sealing materials in return for permission to videotape the process for use in his course. We had a great turnout for the demonstration (~30 people) and had media coverage in the newspaper, radio, and television. It was a good day! Happy well-sealers

Retirement Dinner for Peter Calengas

The Geology Department treated our long-time chairperson to a dinner at Magnolia’s Restraurant in downtown Macomb. Peter will be greatly missed by all of us. He was much more than just our chair, he was our colleague, our mentor, our confidant, and most importantly, our friend. He leadership is directly responsible for the atmosphere of cooperation and collegiality that exists in the Geology Department. We wish him all the best in his well-deserved retirement.

Geology Club Corner

The Geology Club has kept busy the past year with 'Bad Geology Movie Nights', preparing rock and mineral bags, and a trip to a local underground gypsum mine near Burlington, IA. We continue to sponsor and organize our annual Geology Department Holiday Party and our Geology Department Spring Picnic. We also continue to sell WIU Geology water bottles and pint glasses as fundraisers. This year we are considering making WIU Geology coffee mugs. Stay tuned for information about these on the Department of Geology Facebook page. This spring we will once again drive over to the Iowa City area for the MAPS Fossil Show and to visit the Devonian Fossil Gorge. Fun times!

SGE had a productive year. Our shirt sales went very well, we even had to place a second shirt order to meet the demand. We spruced up the sidewalk timescale, but shortly afterward a broken water line and the ensuing sidewalk repair took out the Pennsylvanian, , and Triassic so we have more work to do this spring! The photos below are from our members helping a local group of Webelos work towards their geology pin. Four SGE members and Dr. Bennett showed them our museum, hall displays, and even the rock saws!
