Geology Course Experiences – March 2025

/

Over the past month, the online geology course I am taking has proceeded with 4 more chapters of the textbook, an added role-playing activity on flooding, and a field trip being scheduled for early April! So far, the most thought-provoking chapter has been on water pollution. It is a topic I’ve learned about over a period of years but having a well-organized chapter tie everything I know together was almost overwhelming. The moves to reduce efforts to improve or preserve water quality at the Federal level while I was reading the chapter made the challenges we face near term and into the future even more troubling.

In the lab, there were sedimentary and metamorphic rocks to look at and then some different kinds of labs…looking a cross sections and oceanography. I skipped one of the labs because it was raining, and I decided I didn’t want to be out and about – a benefit of being a retired person. I took pictures of the rocks we looked at in the lab and made ‘flashcards’ for myself to help me learn to recognize them. Of course – the HCl test and scratch plates are also needed for identification too.

 I met my daughter for lunch after most of the lab sessions before heading back home.

Geology Course Experiences – January 2025

/

I started a second semester at Missouri State University in January – taking a geology course (online) and lab (in person). The semester did not start out as well as the one in the fall:

  • Unfortunately for me, the department had made the lab optional so the university’s program for people over 62 only applied to one part – make the semester considerably more expensive than the fall semester.

  • I also mistakenly signed up for an online lecture course that didn’t begin until March (it didn’t occur to me that there would be a schedule like that) so I had to make a quick adjustment to get a course that matched the lab duration.

  • The lecture part of the course (online) had a digital textbook that include study aids that was required for the course….that cost over $80. It was quite a ‘sticker shock.’

The first lab happened before I got the lecture course situation fixed, but evidently it was also before most people in the lab had attended a class too. The instructor walked us through the lab as a group, but she talked to fast that I wonder how many of the students understood it very well. Fortunately it was a topic I was familiar with.

I’ve completed the first two chapters of the textbook that have been assigned – and the associated questions/quizzes. There was one short YouTube video that was included in the assignments. I am disappointed that the professor does not include any recorded lectures for the online course; she did invite us to a similar course that she is teaching in person if we wanted to hear a lecture on particular topics…and I have gone to one.

The course and lab both reference field trips but there were none listed on the schedule for either one. I asked the lab instructor…they only knew that there hadn’t been field trips since COVID. When I emailed the professor, I was told that there would be a field trip in early April. Would it have happened without my query? Geology field trips are some of my favorites. When I was in high school, I went on several field trips with Southern Methodist University’s geology department since I had a friend whose father was a paleontologist there…and then in college I tagged along with my husband’s geology class at El Centro (community college) and University of Texas (rock roses and marine fossils and caves). In Maryland, the master naturalist training included a hike in Patapsco Valley State Park with a geologist! So – I really want at least one geology field trip from this course.

The professor also sent out a pdf with a self-guided geology tour of the campus. I did it last week; the day was too cold to do it leisurely although I did notice non-geology things along the way too.

As I walked from the lecture building toward the first stop on the tour – I made a slight detour to photograph Ozark Witch Hazel that blooms in January. The buds were open but the streamers were still curled…probably because it has been very cold during the past week.

The first stop was to see the “Carthage Stone” (limestone) façade of Carrington Hall. The foundation of the building is Missouri Red Granite from the St. Francois mountains of southeastern Missouri.

Inside the building, there is a tile floor (not a geological feature) and steps/decorative spheres of marble….a grand staircase.

I photographed tiny fossils in the polished limestone stairs of Hill Hall. The building was constructed in 1924…one of the older buildings on campus.

The Memorial Garden near the student union building has a gabbro slab (igneous like granite but with larger crystals and dark silicate minerals like plagioclase feldspar). There is also as sandstone ramp/wall along the walk to the Memorial Garden. The stones are from northwestern Arkansas and reminded me of some sandstone my grandfather used to construct some benches back in the 1960s.

There are dolomite rocks in some of the planting areas – ugly but interesting.

At the southeastern door of the student union, the slab to the right of the door is more Carthage Stone…this time with more visible fossils! The step up to the door is granite porphyry…with different crystal sizes indicating that it had 2 phases of cooling and crystallization.

It had been a cold walk but the exercise of being out and about felt good as I walked back to my car to go home. I am thinking of the walk as the first field trip of the course.

2024 in Review: Travel and Classes

/

2024 was a year we ramped up our travel and educational activities – almost to the pre-COVID levels. Both involve being out and about with groups of people….great opportunities to enjoy the place and engage social skills more frequently. Since we now live in the center of the country rather than the east coast, our travel has been via road trips rather than flying; we are not missing the hassle of airports and rental cars!

The travel included two birding festivals (Whooping Crane Festival and Festival of the Cranes) and a solar eclipse…and frequent trips (at least monthly) to Dallas for family visits.

There are accommodations my husband and I (4 years older than when we travelled pre-COVID) are developing for ourselves to ensure that we feel good when we travel:

  • stretch breaks every hour or so when we are driving

  • exercise regime that works in hotels to minimize aches and pains

  • eating almost the same as we do at home (big meal in the middle of the day, extra veggies for me)

  • keeping our sleep time on central time (if possible)

Both my husband and I have been doing online webinars for a long time. This last fall I re-started in-person classes with the Missouri Master Naturalist Training and a class at Missouri State University (Identifying Woody Plants). The master naturalist training was a path toward creating the level and type of volunteering I had enjoyed in Maryland; it lived up to my expectation of continuing the transition to ‘Missouri as home.’

The university class was the first time I had taken a university class since the 1980s and was something to savor because of that and the topic/professor/other students; I found that taking a university class without the pressure of needing a grade or hurrying off to my job was pleasantly different from any of my prior experience.

2024 was a year that saw us settled in our new home in Missouri and increasing both our travel and in-person classes activity. The travel will be sustained (or increased slightly in 2025). The in-person classes might be reduced since there is nothing equivalent to another master naturalist core training, but my volunteering in 2025 is likely to be significantly more than it was in 2024.

Identifying Woody Plants (Month 2)

/

The Identifying Woody Plants field class I am taking at Missouri State University has met 5 more times since my last post about the field sessions on the campus.

I am continuing to take pictures of items in the classroom before class:

An opened Maclura pomifera (Osage orange) fruit

Some Quercus macrocarpa (Bur oak) acorns

An herbarium page showing Tilia americana (American Basswood) fruit which we have seen in the field, but my pictures were not very good.

Cuttings from two plants were brought in and we were asked to ID them based on our notes – with the hint that the first one had milky sap (hard to see since it had been cut):

Morus alba (white mulberry) – a non-native that is frequently seen as a ‘weed’ tree and Vitis (grape).

Recently the walk from the parking lot to the classroom building has been full of late blooming pollinator plants and fall foliage.

The one session where we stayed on campus added some new trees to our list:

Quercus bicolor (Swamp white oak)

Sassafras albidum (Sassafras)

Carya ovata (Shagbark hickory)

Quercus lyrata (Overcup oak)

We also saw some review trees and I got better pictures of Celtis occidentalis bark (Rough hackberry)

And some add odd growth of a Liriodendron tulipifera (tulip/yellow poplar). The trunk of the tree was growing at a slant rather than straight upward and it had small branches coming out relatively close the ground.

The hikes on campus and further afield have been more pleasant this past month because the temperatures have been cooler. There have been no rainy days in the field either!

Busiek State Forest and Wildlife Area

/

A sunny fall day…the Identifying Woody Plants Class spent a couple of hours at Busiek State Forest and Wildlife Area – adding 9 more woody plants to our list and seeing others that were already on the list and we practised our ID skills for them; there are now 78 woody plants that we should recognize and be able to supply the common name, family, and scientific name!

We encountered an Osage Orange (Maclura pomifera) – a tree we’d seen in previous classes - that had leaves that hadn’t fallen before the first hard frost. All of us began to realize how changed identification was going to be without leaves on the trees!

The first new one was Box Elder (Acer negundo) – the only maple with compound leaves. ID is helped by its green branches.

The second new tree was Spicebush (Lindera benzoin) – still with leaves and one I had seen recently in a Missouri Master Naturalist field trip. The picture I took was of a male but there were female trees with red fruit that we saw at Busiek.

 American Sycamores (Platanus occidentalis) were growing along the dry creek bed…another tree that we reviewed. The very large leaves were still mostly on the tree.

The third new tree was the Carolina willow (Salix caroliniana)…also growing close the dry creek bed. Its leaves are a little bigger that the Black Willow’s…and the stipules tend to stay on rather than falling off. It still had leaves…everyone realized it was a willow of some kind.

I couldn’t resist taking some pictures from the dried creek bed. The fall color is a bit muted this year because it has been so dry here. I noticed some wasp apartments on one of the bridge support columns.

Another review tree – the honey locust (Gleditsia triacanthus) – and I finally got some pictures of thorns. I also picked up a seed pod to put in the tree educational trunk I am creating for Missouri Master Naturalist.

The fourth new tree was the Chinkapin oak (Quercus meuhlenbergii). I didn’t get any good pictures of it!

The same was true of the fifth new plant – a vine: Greenbrier (Smilax). Supposedly it might be something that will be easier to see and ID in the winter because the stems stay green….and the thorns would be on the vine too – to mistaking it for a grape (Vitis).

Smooth sumac (Rhus glabra) was the sixth addition for the day. The plants did not have the distinctive seed heads because they tend to get cut down frequently so that they don’t take over the area where they are growing.

Persimmon (Diospyros virginiana) was our seventh new plant. The fruits looked beautiful, but no one was willing to try them quite yet. I am glad I have planted some in my yard and hope to enjoy them at perfect ripeness in the future.

The eighth new plant was a native woody grass/bamboo: giant cane (Arundinaria gigantea).

The ninth (and last) new plant for the day was an Eastern Cottonwood (Populus deltoides). Most of the leaves were gone…but the one we looked at was a huge tree with deeply grooved bark and buds ready to go for next spring.

It was a good walk and a transition point for the way we will begin to identify trees by characteristics other than their leaves.

Phelps Grove Park

/

Last week the Identifying Woody Plants class walked to Phelps Grove Park to add more trees to our list. I used my point-and-shoot (Canon Powershot SX730 HS) to capture some features of the additional trees (plus some trees already on our list). The temperaature was in the 70s…perfect for the hike…but the leaves are beginning to fall on many of the trees. Identification will get harder.

Serviceberry – Amelanchier arborea – Rosaceae: stripped bark, multiple trunks, small trees, two toned pointy buds, leaves simple and alternate

Crabapple – Malus – Rosaceae: pome without grit, twigs hairy, leaves (lobed, simple, entire)

Hawthorne – Crataegus – Rosaceae: thorns, pome, leaves round, bark pealing and patchy, the one we saw was infested with apple cedar rust (i.e. not a healthy tree)

Fig (just for interest…not added to list)

Flowering dogwood (not new) – Cornus florida - Cornaceae

White oak – Quercus alba – Fagaceae: leaves (rounded lobes, smooth, lighter underneath), acorns dark with bumpy cups and often sprout in fall

Hemlock (not new) – Tsuga canadensis - Pinaceae

Black cherry – Prunus serotina – Rosaceae: observed bark…branches too high to see more

Osage orange – Maclura pomifera – Moraceae: bark shaggy and orange in parts, leaves (tapering tip, entire, alternate, simple, size varies), the one we saw was male so no fruit

Red mulberry  - Morus rubra – Moraceae: milky sap, leaves (toothed, shiny, falling)


Shortleaf pine (note new) – Pinus echinate – Pinaceae

Hackberry – Celtis occidentalis – Cannabaceae: drupe that can taste like a dry raisin, leaves (3 veins, asymmetric, rough), the one we saw had galls, bark rough and gray, large tree

Shingle oak – Quercus imbricaria – Fagaceae: acorn small, leaves (no lobes, long and narrow, soft hair underneath), multiple buds at tend of twigs, bark grayish

Identifying Woody Plants (Month 1)

/

The Identifying Woody Plants field class I am taking at Missouri State University has met 5 times. There have been two off-campus field trips that I’ve posted about previously: Springfield Botanical Gardens and Lovett Pinetum. The other sessions have included walks around the MSU campus identifying trees. Just as in the off-campus field trips, I’ve tried to get good pictures of the trees so that I can include them in my PowerPoint based ‘flashcards’ to help me learn all the woody plants presented in the class (even though I am not taking the class for credit).

In the first class, I tried using my cell phone…juggling it with my small notebook for note taking. It did not work so well; I only got reasonable pictures for three of the trees we encountered.

Black gum – Nyssaceae – Nyssa sylvatica

Buckeye – Sapindaceae – Aesculus

For the next campus walk – I used my small point-and-shoot camera and managed more pictures. I had front pockets for both the small notebook and the camera. It was a very hot/sunny day; I wore my fingerless gloves to keep my small notebook dry. I did not feel well during the later parts of the walk even though I was drinking plenty of water.

American Sycamore – Platanaceae – Platanus occidentalis

Yew – Taxaceae - Taxus

Flowering dogwood – Cornaceae – Cornus florida

Bald cypress – Cupressaceae – Taxodium distichum

Shortleaf pine – Pinaceae – Pinus echinata

American basswood – Malvaceae – Tilia americana

The third walk around campus was easier; I had my system for juggling the notebook and camera…and it wasn’t quite as hot. I also wore my hiking boots, so my feet did not hurt like they did on one previous campus walk. I am still not managing to photograph everything during the walk; for the ones I miss (i.e. not listed in this post) I glean photos from the class charts and/or web searches to populate my study Powerpoint.

Red Maple – Sapindaceae – Acer rubrum

Burning bush – Celastraceae – Euonymous alatus

Northern red oak – Fagaceae – Quercus rubra

Northern catalpa – Bignoniaceae – Catalpa speciosa

Yellow poplar – Magnoliaceae – Liriodendron tulipifera

True cedar – Pinaceae - Cedrus

Siberian elm – Ulmaceae – Ulmus pumila

Sweet gum – Altingaceae – Liquidambar styraciflua

Pin oak – Fagaceae – Quercus palustris

Honeylocust – Fabaceae – Gleditsia triacanthos

There is some memorization involved…but I am beginning to find that I remember the scientific names as well as the common names as I continue to study…adding new woody plants to the list each week. The class is living up to my expectations in helping me expand my identification skill of woody plants of Missouri.

Registering for a College Class

/

I registered for a class at Missouri State University last week – Identification of Woody Plants. It has been over 40 years since I did this last! Lots has changed in those years.

  • I didn’t need to go through an admissions process ahead of time or get transcripts sent because I am part of the cohort of people over 62 years old that can attend classes at much reduced cost (MSU 62). I called their office a week before the registration day to confirm. I also asked about the pre-req for the class I wanted to take; I had the pre-req in my long-ago college experience but without the transcript, how would they know? I was advised to email the instructor to get a waiver…which I did and they waived the pre-req for me.

  • The course catalog and schedule are all online now rather in paper/soft cover books. I knew that there were only 7 slots remaining in the course I wanted to take before I headed to registration.

  • The registration for the MSU 62 cohort was held the week before classes started which is later than I usually registered back in the 70s. I arrived just after they opened. The receptionist for the event handed me forms and sent me to tables/chairs to fill them out. The course I wanted to take was not on the paper version of a course list on the tables, so I was glad I had the numbers for it written down to enter in the appropriate places on the form. I also had the printed version of the email exchange with the instructor. I was so focused on the requirements for my degree 40 years ago…now I am just taking whatever interests me and not for credit.

  • When I finished the forms, I joined the queue in chairs waiting for advisors…and thoroughly enjoyed a donut while I waited. I don’t remember ever having food provided when I registered for college classes before!

  • The advisor got me admitted and registered very quickly. She discovered that I already had a number with the university (maybe because I had donated back in 2020).

  • After that I was routed to a second person that printed out my concise schedule and talked to me about setting up my computer accounts, books and parking permits. It appears that the only cost is going to be for the parking pass – quite a bargain even compared to the costs I had in the 1970s. In addition, the textbook for the class I am taking is listed as ‘optional’ so I am waiting to buy it until after I hear what the instructor says in the first session.

Less than an hour after I entered the building, I was walking back to the parking garage. Along the way I photographed the colorful school mascot (bear) at the corner of the building. I am looking forward to this course…not so different from the way I always looked forward to the fall during my education-intense years…but savoring that I won’t be taking any tests!
