CHRISTCHURCH, NEW ZEALAND–Our Wooster Geologist in New Zealand, junior geology major Andrew Collins, is on an enforced break from his studies at the University of Canterbury. (The earthquake damage and the continuing aftershocks have given Andrew a new perspective on neotectonics.) Like any good geologist, he took the opportunity to see more of the land. One of his visits was to Westland Tai Poutini National Park on the northwestern coast of South Island. There he saw the Franz Josef and Fox glaciers descending from the Southern Alps into a coastal rainforest. You can see more of Andrew’s photographs and read his narratives on his blog. This year Wooster Geologists also had close encounters with glaciers in Iceland and Alaska.

Wooster Paleontologists in Indiana!

RICHMOND and LIBERTY, INDIANA–The College of Wooster Invertebrate Paleontology class had its field trip today to sunny eastern Indiana. We collected bags and bags of fossils from Upper Ordovician strata for research projects throughout the rest of the course. Each student will be reconstructing a paleocommunity from the fossils, and along the way will learn several paleontological techniques and principles. Our specimens include many strophomenid and orthid brachiopods, trepostome and cyclostome bryozoans, rugose and heliolitid corals, crinoids, nautiloids, a few trilobites, and some mystery fossils I find perplexing. (Always scientific opportunities there!) We hope to show some of our discoveries in later blog posts.

The challenge of this trip was the size of the group: 21 people in five vehicles. It all worked out well for a spectacular field day.

Hederelloids: Pulled from obscurity! (Well, maybe …)

PARMA, OHIO–This afternoon I gave a talk at a meeting of the North Coast Fossil Club in this suburb of Cleveland. I chose the poorly-known fossil group called hederelloids as my topic because I knew that many people in that enthusiastic group had likely seen and collected them without knowing. They are very common encrusters on Devonian fossils, especially brachiopods, corals and bryozoans from the Middle Devonian of northwestern Ohio. I was not disappointed as several keen members brought me specimens from their collections or told me about large numbers of hederelloids they can send to me for study. Paul Taylor and I have been studying hederelloids for the past five years (as far as I know we are the only paleontologists in this little subfield!) and believe they may hold a key to some curious events in the Devonian and may expand what we know about lophophorate evolution. We need many more specimens, though, for our systematic work. The hard-working, knowledgeable amateur paleontologists in the North Coast Fossil Club are now going to help! Here is a link to the PowerPoint slides of my hederelloid talk. If you just have to know more, here’s a 2008 Taylor and Wilson hederelloid paper as a pdf.

I very much enjoyed talking with members of this club. They love fossils for their beauty, complexity, and historical wonder. To be able to contribute to science is a bonus.

The New Zealand Earthquake: A Wooster Geologist Eyewitness Report

CHRISTCHURCH, NEW ZEALAND–Andrew Collins is a Wooster geology student studying abroad at the University of Canterbury in Christchurch, New Zealand. Here is his account of Saturday morning’s earthquake:

Just got another tremor as I sat here writing! Certainly is active!

I don’t really know what to say! It was definitely an odd feeling being awoken at 4:30 am to violent shaking. My room’s on the third floor and hangs out right over the walkway, so my first instinct was to get out of there and move toward the support structure of the building. I had a pretty hard time walking down the hallway – eventually I just gave up and sat on the couch and waited for it to subside, at which I point I got dressed and left the building.

I went downtown with one of my flatmates and took these pictures. It was a bit of a mess. We managed to get there before the police had closed off everything, so we got to go some places we probably shouldn’t have. Cars were crushed; facades had been torn from buildings and had basically fallen face-first into the street; fire trucks, police cars, and ambulances were going every which way; and bulldozers were being unloaded off flatbeds at every street corner. It definitely seemed a bit like a dream. I guess the most important thing is that nobody got killed. That’s pretty incredible when you figure that Christchurch is a city of 315,000 sitting on loose soil at the edge of the Pacific Ocean (sounds like a certain other city prone to earthquakes, no?).

(Another tremor)

The ground hasn’t actually stopped moving since the earthquake (it’s been about 32 hours now). It’s constantly trembling and then every once in a while there’s a noticeable aftershock (between 3.0 and 6.0 – most probably between 3 and 4).

Shopfront in Christchurch, New Zealand.

(Andrew Collins will be adding more text and images about the earthquake to his blog later this week. We are very pleased that he is doing fine, and our thoughts go out to the Christchurch community as they begin their recovery.)

Wooster Geologist Experiences New Zealand Earthquake — Story Will Follow

CHRISTCHURCH, NEW ZEALAND–Wooster geology student Andrew Collins is studying abroad in Christchurch, New Zealand, this semester and was there during the 7.1 magnitude earthquake early Saturday morning. He is fine and I hope will be able to send us his story and some photographs later. We have two earlier posts from him about his New Zealand field experiences with amazing karstic weathering and basalt exposures.

Although this powerful earthquake produced “significant damage“, there are no reports yet of any deaths. It appears to have been an unusually complex tremor — maybe three earthquakes in quick succession. Andrew can tell us how it felt as the jolts woke him up. We are very pleased he is OK.

Finishing our Tour of Yellowstone

After hiking through the Tetons, we continued our tour of Yellowstone by visiting a number of places in the eastern and northern portions of the park. We visited Signal Mountain Summit, which is a great overlook of the glacial outwash plain due to the glaciation of Yellowstone. (However, I was just as fascinated by the little black bear that we saw on the drive up to the summit.) We also stopped at Artist Point, south of Canyon Village. (We actually stayed the night in Canyon Village’s cabins.)

Then, our journey took us to Norris Geyser Basin, Obsidian Cliff, Sheepeater Cliff, and the Mammoth Hot Spring Terraces. All I can really say is “Wow”!!

Above is a scenic view of one section of Norris Geyser Basin, which had some of the most interesting thermal activity in the park.

Take a look at Sheepeater Cliff, which is composed of basalts that exhibit columnar jointing.  Sheepeater Cliff is a result of the bimodal volcanism that was present in Yellowstone.

Mammoth Springs provided some wonderful exposures of travertine terraces, several of which were very active.

Of course, along our journey we made some friends, such as this moose grazing along the river bank.  It was amazing how one creature could tie up so much traffic!!

The day ended with a trip to the Gardner River.  The picture above shows a small stream of thermally-influenced water flowing into the Gardner River.  Along the river bank, temperatures are easily over 100-110 degrees F, and thus many people enjoy one of nature's very own hot tubs.  But, if you walk just a few feet out into the main portion of the Gardner, the water is ice cold.

Hiking in the Tetons

Due to such great weather, the group decided to go for a 9.6 mile hike (4.8 miles up and up and up and then back down again). We hiked the Lupine Meadows Trail NNW of Moose, Wyoming — in Grand Teton National Park. This specific trail takes you to Amphitheater Lake, which is nestled in between Grand Teton and Middle Teton. It was an absolute fantastic hike, with several switchbacks along the way.

At the very top of our hike, we came upon Amphitheater Lake, which is located at 9,698 feet above sea level.  Because I'm a big fan of oxygen, I noticed that I was not quite in Ohio any more.  The hike provided us with a 2,960 foot elevation gain above the valley; therefore, there were spectacular views!!

From Bozeman to Yellowstone to Jackson Hole

The Teaching in the Field Workshop left Bozeman for a whirlwind tour of Yellowstone and the Tetons. Our goal was to actually think about teaching in the field — while in the field!! Some of us concentrated on how we could incorporate our surroundings (particularly Yellowstone) in modules for specific courses that we teach; others of us were more focused on devising a department field trip. I could not think of better surroundings. The field trip leader was Dave Mogk, petrologist at Montana State University, who has done much research in the area.

On the first leg of our journey from Bozeman to West Yellowstone, we stopped at a talc mine just south of Ennis, Montana. The talc mine is within the Montana metasedimentary terrane in a marble-hosted deposit. Nearby, we also looked at algomin-type banded iron formation exposures that contained small isoclinal folds. Afterwards, we headed toward Hebgen Lake to view the site of the 1959 earthquake that registered 7.5 on the Richter Scale and then onward to West Yellowstone.

When in Yellowstone, we were able to visit a number of locations, but we only concentrated on the western and southern portions of the park. Never being to Yellowstone before, I was able to visit Fountain Paint Pot in the Lower Geyser Basin and Grand Prismatic Spring, before driving south toward Grand Teton National Park. Along the way, Dave introduced us to the regional geology, discussing such topics as the Huckleberry Ridge, Mesa Falls, and Lava Creek eruptive events, the Absaroka volcanics, the thermal anomaly vs mantle plume argument, and the structural history of the area.

Above is a photo of Spasm Geyser, located in the Lower Geyser Basin.
