Wooster Geologist/Historian on the San Andreas Fault

June 17th, 2017

Berkeley, California — Brandon Bell (’18) is a double major in geology and history at Wooster. He has a classic double-major thesis that combines both disciplines: the early history of modern seismology following the Great San Francisco Earthquake in 1906. He is focused on the growing international communications among scientists about earthquakes, especially between Japan and the United States. Brandon thus is studying the geology of earthquakes as well as original documents generated through these international discussions. Brandon received Copeland Funding from the college to visit the Bay Area of northern California to work in the libraries and visit the San Andreas fault itself. The above image is of the beautiful University of California campus in Berkeley.

Brandon has his own detailed and illustrated blog describing his adventures. Check it out! He is still adding to it.

Special thanks to Dr. Peter Roopnarine at the California Academy of Sciences for meeting with Brandon and adding to his knowledge and experiences.

Wooster’s Fossil of the Week: A naticid gastropod from the Pliocene of southern California

October 28th, 2016

polinices-galianor-sd-pliocene-1-copyThis week’s fossil comes from our teaching collection. It’s label appears to be from the late 19th Century. It is a naticid gastropod (“moon snail“) listed as Polinices galianor. That name, which I can only find in two lists and never with an author, may be a corruption of Polinices (Euspira) galianoi Dall 1909. It was collected from the Pliocene of San Diego County, California. It is preserved as both an internal mold and thin sheets of remnant original shell.

polinices-galianor-sd-pliocene-2-copyThis is a view of the underside along the axis of coiling. The hole is known as the umbilicus and is distinctive for the naticids. These snails are predatory, moving through loose sand with a very large foot and capturing shelled prey, like clams and other gastropods. They then drill a beveled hold through the shell of the prey with specialized teeth in their radulae. We’ve discussed the trace fossils they leave (Oichnus) in a previous post.

The genus Polinices was named in 1810 by Pierre Dénys de Montfort (1766–1820), a French malacologist (one who studies mollusks).

screen-shot-2016-10-22-at-11-49-26-amThis brief paragraph is all it took in the early 19th Century to name a new taxon. The system is much more elaborate now.screen-shot-2016-10-22-at-8-20-44-pmPierre Dénys de Montfort is a tragic figure in science. First, he had the misfortune of being a French intellectual during the chaos of the French Revolution and the resulting Napoleonic dictatorship. Scientists struggled then, but after service in the revolutionary army and an apprenticeship with a geologist, de Monfort gained a position in the Jardin des Plantes, a research botanical garden in Paris. He did a massive study of mollusks, producing systematic tomes. De Monfort was a whiz at languages, so he did well as a translator after Napoleon was  finally defeated in 1815 and the Allied armies occupied Paris. Then he went off the rails. He had since 1801 championed the reports of mariners that giant cephalopods occasionally rose from the sea and attacked shipping, as shown in his above print (de Monfort, 1801, p. 256). The modern roots of the kraken! De Monfort took the idea too far, was ridiculed in the scientific community, and eventually died of starvation and alcoholism in the streets of Paris in 1820. The later discovery of giant squid salvaged his reputation a bit, but no one has yet found evidence of “le poulpe colossal”.

Field Work on Black Mountain

May 21st, 2016

San Diego, CA – Amineh AlBashaireh (’18) and I are working with USD scientists, Dr. Bethany O’Shea, Elizabeth Johnston, and Eric Cathcart on the geology of Black Mountain in San Diego, CA.

Black Mountain Open Space Park is a popular hiking and mountain biking destination.

Black Mountain Open Space Park is a popular hiking and mountain biking destination.

The Santiago Peak Volcanics are exposed in the park. These rocks are early Cretaceous in age (~110 Ma) and are thought to represent the volcanic arc associated with the Peninsular Range batholith (Herzig and Kimbrough, 2014).

Slightly metamorphosed andesites and basaltic andesites are present as gray to dark gray aphanitic (fine grained) rocks with scattered phenocrysts (crystals) of plagioclase.

Hikers and bikers who visit Black Mountain may be less familiar with its volcanic history and more familiar with its mining history. In the 1920s, this area was briefly mined for arsenic. The arsenic was used in pesticides at the time.

In the mine waste, you can see shiny gold specs of aresenopyrite (FeAsS). Arsenopyrite is a sulfide mineral in which some of the sulfur is replaced with arsenic.

Amineh is studying trace element concentrations in the soils on Black Mountain. Here she is collecting samples. In the next few days, and over the course of the summer, we'll show you how she processes these samples in the lab.

This was a small (~30 cm) rattlesnake that we saw earlier in the day, and we take field safety seriously, so when we heard a rattle coming from the tall grass, we ended our sampling and called it a day.

Wooster’s Fossil of the Week: A tectonically-deformed Early Cambrian trilobite from southeastern California

April 10th, 2015

Olenellus terminatus whole 585This wonderful trilobite was found last month by Olivia Brown (’15), a student on the Wooster Geology Department’s glorious field trip to the Mojave Desert. Olivia collected it at Emigrant Pass in the Nopah Range of Inyo County, southeastern California. It comes from the Pyramid Shale Member of the Carrara Formation and is uppermost Lower Cambrian. It appears to be the species Olenellus terminatus Palmer, 1998. It is a great specimen because most of the body segments are still in place. At this locality we find mostly the semi-circular cephalon (the head) separated from the rest of the body. The species O. terminatus is so named because it represents the last of its famous lineage of Early Cambrian trilobites. The last time we found such a whole trilobite at this site was in 2011, with Nick Fedorchuk as the paleo star of the day.

This trilobite has been tectonically strained along its main axis, giving it a narrow look it did not possess in life. In fact, these trilobites with their semi-circular cephala make nice indicators of the strain their hosting rocks have experienced.
spines 032515 585This particular kind of trilobite has very distinctive spines, as shown in the close-up above. The long spine on the right comes from the trailing edge of the cephalon and is called a genal spine. The one in the center is a thoracic spine emerging from the third thoracic segment. The primary role of these spines was probably the obvious one: protection from predators. They may also have helped spread the weight of the animal across the substrate if they were walking across soupy mud (much like a snowshoe).

We’ve met this man before in this blog. James Hall (1811–1898) named the genus Olenellus in 1861. He was a legendary geologist, and the most prominent paleontologist of his time. He became the first state paleontologist of New York in 1841, and in 1893 he was appointed the New York state geologist. His most impressive legacy is the large number of fossil taxa he named and described, most in his Palaeontology of New York series. James Hall is in my academic heritage. His advisor was Amos Eaton (1776-1842), an American who learned his geology from Benjamin Silliman (1779-1864) at Yale. One of James Hall’s students was Charles Schuchert (1856-1942), a prominent invertebrate paleontologist. Schuchert had a student named Carl Owen Dunbar (1891-1979). Schuchert and Dunbar were coauthors of a famous geology textbook. Dunbar had a student at Yale named William B.N. Berry (1931-2011), my doctoral advisor. Thus my academic link to old man Hall above.

Exploring the Tecopa region … and finally the trilobites!

March 14th, 2013

SaltSpring031413ZZYZX, CALIFORNIA–This was our last full day of geological adventures in the Mojave Desert for 2013. The weather was even warmer than yesterday, with the temperature in Baker at 4:00 p.m. a delightful 94°F. We began in the usual way from our temporary home at the Desert Studies Center, heading north of Baker again to Shoshone and the Tecopa area. Our first stop was at Salt Creek Spring in the Salt Spring Hills, one of the rare riparian environments in this part of the desert. This place is also notable as the first place gold was found in southern California. This discovery in 1849 began the boom in mining throughout the Mojave Desert.

TafoniMelissa031413One of the interesting geological features we noted was the occurrence of the familiar tafoni, but this time in a deeply eroded outcrop of quartz monzonite (shown above with Melissa Torma). Our companion Yoav Avni believes this may represent a Pleistocene pluvial phase of erosion that has been exhumed in the modern landscape. Tafoni features in granite would seem to require more water than is present today in this system, thus placing these features during a wet interval makes sense.

ShoshoneMuseum031413We next returned to the little settlement of Shoshone, this time visiting the town museum (above). It is well worth touring for its local artifacts, some wildlife displays, and the bones and teeth of the Shoshone Mammoth found in the Tecopa lake sediments.

Archidiskodon_tamenensis031413The mammoth (Archidiskodon tamenensis on the sign) has been very well preserved by the lake clays and silts, especially the diagnostic teeth and jaws. It is an impressive find and an important addition to our knowledge of the ancient Lake Tecopa ecosystem.

OliviaBrownResting Springs031413The Resting Springs Welded Tuff exposed east of Shoshone is one of the most famous roadcuts in the Mojave Desert. Above we see Olivia Brown exploring the glassy black middle of the unit. The colors and hardnesses of the rocks here show degrees of welding from the intense heat developed in this pyroclastic flow. It is technically a devitrified pumice tuff, welded tuff, and vesicular vitrophyre dated by K-Ar methods as 9.5 million years old. The fiamme are fantastic.

JonahDragFold031413In the same outcrop of the Resting Springs Tuff are some impressive faults. Jonah Novek is showing above how he knows this is a normal fault because the drag fold shows downward movement of the hanging wall (the side he is standing on).

TrilobiteCollecting031413At lunchtime we arrived at Emigrant Pass east of Tecopa to collect trilobites from the Cambrian Carrara Formation exposed on the north side of the highway (which happened to be the Old Spanish Trail). After a bit of exploring, our ace field geologist Shelley Judge found the most fossiliferous outcrops. We found hundreds of the fascinating critters, leaving most for future field trips. I like the view above, by the way, because it shows Telescope Peak on the far distant skyline.

TrilobiteWhole031413The best trilobite of the day (and there were many good specimens) was collected by Olivia Brown. It is a rare whole specimen, apparently of the genus Olenellus. You can see all the thoracic segments and spines, as well as the pygidium. The way the cephalon is separated from the thorax may indicate that it is a preserved exuvium (molt). Very nice.

ChinaRanchSign031811aFollowing a geological tradition transferred from Sonoma State University geologists to us via my friend Matthew James, we visited China Ranch south of Tecopa and had date milkshakes. Delicious and refreshingly cool on what turned out to be a very hot day. We also had a good geology lesson with the fanglomerates and ancient lakebeds exposed around the date groves.

TecopaPlaya031413While driving out of Tecopa, we stopped to walk out onto the Lake Tecopa playa, which was covered by a thin crust of salts. From the left are Meagen Pollock, Melissa Torma, Shelley Judge and Olivia Brown. We observed the modern playa sediments juxtaposed with the ancient lake strata exposed as low mounds.

WadeExit031413Last of all was a stop to briefly recognize the Harry Wade exit route out of Death Valley at an historical marker on the highway back to Baker. We came full circle at this point, since we started with Death Valley and now ended looking back into that source of such hardship in 1849.

Our final scientific event of the day was an excellent tour of the night sky by the Laboratory Technician of the Vassar College Environmental Sciences and Geography Department, Rick Jones. The sky is very dark and inviting in this lonely part of the desert.

Enjoying the geology of the Mojave National Preserve

March 13th, 2013

StudentsLavaCave031313ZZYZX, CALIFORNIA–Today the Wooster Geologists explored the Mojave National Preserve. It is a beautiful, spacious, diverse place well maintained and protected by the National Park Service. Our first stop of the morning is shown above. We explored a lava tube in the cinder cones portion of the preserve. We descended into the dark tunnel by the steps above, and then studied the walls and ceiling with our flashlights, as Melissa Torma is doing below.
MelissaCave031313Lava tubes are formed when a lava flow cools on the top and sides, and then the remaining lava flows out, leaving behind the empty shell. In this particular lava tube we could see various level markings the lava left on the walls as it drained away. We also saw spatter and “lavacicles” hanging from the ceiling much like icicles or stalactites in a cave. My favorite part is where we can see from below a granitic boulder that was caught up in the flowing lava.
CambrianLimestoneOutcrop031313South of the lava tube along Kelbaker Road is a small outcrop of Cambrian limestone. We examined these rocks for a short time (above) to sort out their lithologies and the paleoenvironment in which the sediment accumulated. The clues included extensive and diverse horizontal burrow systems (shown below) and numerous oncoids with shelly nuclei.
BurrowsLimestone031313The students determined that the burrows were filled with dolomite from later diagenesis of the sediment, and that the oncoids showed the system was deposited well within the photic zone. We think this rock is a biomicrite formed around the storm wavebase on a shallow carbonate platform.

KelsoDunes031313One of our favorite places is Kelso Dunes. These massive piles of sand are stabilized at their bases but still moving about at their crests. We’ve studied them so many times in the Desert Geology and Sedimentology & Stratigraphy courses that we needed to say little about them. The students raced to the top, noting the diverse sand composition (so much more than just quartz) and eolian structures on the way.

TafoniAnanda031313Ananda Menon is here showing us one of the magnificent tuff beds at the Hole in the Wall locality in the easternmost portion of the Mojave National Preserve. The holes in the wall (is that how the place was named?) are examples of tafoni, a rock weathering pattern. We hiked the Rings Loop Trail examining the tuff units and their diverse clasts, including pumice and charcoal. We also saw good examples of Indian petroglyphs of unknown age.

QtzMonzoniteCimaDome031313While crossing Cima Dome on the way back to Zzyzx, the group visited an outcrop of quartz monzonite which forms at least part of the intrusive body under the uplift. As with most of our outcrops, it was a story of both petrology and structural deformation.

AlienFreshJerky031313Finally, at the end of the day I could not resist taking the Wooster Geologists to the unique store in Baker called “Alien Fresh Jerky“. Half the group loved it, the other seemed offended by the epic cheesiness. At least Melissa Torma and Jonah Novek enjoyed meeting members of the Galactic Peace Patrol parked in front.

Folded rocks, volcanoes, and a little of the Old West

March 12th, 2013

CalicoMemberFolds031213ZZYZX, CALIFORNIA–The spectacular set of folds above are exposed in the lower parking lot of Calico Ghost Town near Barstow, California. This is a famous site that has been visited by hundreds of geologists, but there are still many mysteries about the causes of this deformation and even the correlation of these rocks in the region. The section makes up the Calico Member of the Barstow Formation, which is apparently below the exposed units of the Barstow Formation in Owl Canyon and Rainbow Basin we saw yesterday.
ShelleyCalico031213As a true structural geologist, Shelley Judge is here explaining the folding of these beds with her hands and, later, a sketch on notepaper. “Explaining” is not quite the right word: she wrangles information and observations out of the students first before developing the deformation hypotheses. It is not just about a bit of compression!
StudentsCalico031213After exploring a wadi west of the town, we then spent the rest of the morning in Calico. The students above (from the left, Kyle Burden, Steph Bosch, Sarah Frederick, Olivia Brown and Alex Hiatt) are enjoying the main street of this reconstructed 1880s mining community. There are lots of attractions here, from sarsaparilla in the saloon to a classic old-timey mystery shack. One gentleman, hearing that we were geologists, kindly explained to us how Calico Mountain is an extinct volcano with “sandy dikes” full of metals and remnants of lava flows on its sides. It was fun to see our students grapple with the question: do we correct this nonsense or just smile and avoid the hassle? (I just let it pass because I was hungry for lunch!)
AmboyCrater031213In the afternoon we drove south and east along Interstate 40 and Route 66 (yes, the Route 66) to Amboy Crater (shown above). The day had warmed considerably — my thermometer said it was now 94°F. Nevertheless, the stalwart geology crew walked to this gorgeous cinder cone and climbed to its rim from the inside (shown below). I enjoyed learning about the subtle features of the lava flows that emanated from the cone, including pressure ridges and hexagonal cooling joints. This flows and the cinder cone look amazingly fresh. The lava flows have been dated at between 6000 and 500 years old.

Verbena031213The warm temperatures at Amboy brought out some reptiles, to our delight. We saw at least three desert iguanas and many flowers, including the Sand Verbena (Albronia villosa) shown above. It felt like summer, although we were still in the middle of March. Tomorrow is expected to be even warmer. (Yes!)

Wooster Geologists in ancient lakes

March 11th, 2013

Manix031113ZZYZX, CALIFORNIA–Today Team Mojave studied the remains of ancient lake systems in the dry, dry desert. Early in the morning we drove west from Zzyzx to the Harvard Road exit off Interstate 15 and took a series of sandy roads to Bulwada Ridge on the shoreline of ancient Lake Manix. This Pleistocene, pluvial lake occupied a huge basin east of Barstow, California. Above we see laminated muds deposited in the lake itself. In the foreground are bouldery shoreline sediments. In the background you can see a scarp cut by the modern Mojave River (all underground at this point). Lake Manix was fed by the ancient Mojave River and supported a diverse fauna of fish and invertebrates.

MeagenBeachRidge031113Just to the north of the shoreline are long, twisting gravel bodies. Meagen Pollock is pondering one which has been truncated by modern erosion and now is topped by a beautiful desert pavement. (She found a beautifully polished artifact on one of these surfaces, by the way. It is a scraper with one bifacially-worked edge.) These gravel deposits are ancient beach ridges made by storm waves on Lake Manix.

OwlCanyonGroup031113After our visit to Lake Manix, we traveled to much older lake and river deposits in the Barstow Formation (Upper Miocene) exposed in Owl Canyon near Barstow. Our tradition here is that the students first explore the exposures and then bring back rocks to the picnic area for group analysis and discussion. The students above are clearly happy with all that they learned. (The two distinguished people in the background, by the way, are my parents Gary and Corinne Wilson who came to enjoy the geological fellowship.)


A view from the other side of the table. Photo by Gary Wilson.

DesiccationCracks031113Kyle Burden found this beautiful example of two-stage desiccation cracks, preserved here as molds in the overlying sandstone.

RainbowBasin031113Another Wooster tradition is the group photograph in front of the outstanding syncline in the Barstow Formation exposed in nearby Rainbow Basin.

AftonSide031113Our final stop was in Afton Canyon about 50 miles east of Barstow. This narrow passageway is where Lake Manix drained into Soda and Silver Lakes, apparently more than once in a catastrophic manner. We crossed the mighty Mojave Rover on foot and then walked up this side canyon to check out the flood deposits and the lake deposits high on the skyline. These mark the highest level Lake Manix reached before it overtopped its dam and drained very quickly.

Another stimulating day which ended with a chicken dinner at the Desert Studies Center. Tomorrow we will return to the Barstow region but this time concentrating on structural issues and volcanic and plutonic rocks.


Death Valley Days

March 10th, 2013

BadwaterGroup031013DEATH VALLEY, CALIFORNIA–All geologists love Death Valley. No other place on Earth has such extraordinarily diverse geology combined with a modern infrastructure and a century of scientific study. The Wooster Geologists had a spectacular time in and around the valley today. Here we are above with the traditional group shot at Badwater. The weather could not have been better.

Zabriskie031013We left the Desert Studies Center at Zzyzx just after breakfast and drove through Baker and Shoshone to the southern end of Death Valley, seeing many wonderful sites. After lunch at the new National Park Service Furnace Creek Visitor Center, we then drove east and up out of the valley to Zabriskie Point. The above view has been published countless times by geologists and nature enthusiasts, but it has not lost its graphic power. We are looking here to the west at deeply eroded lake sediments of the Furnace Creek Formation. Towards the back of the light-colored material you can just make out the black streak of a basaltic intrusion.

ZabriskieOtherSide031013I think the other side of Zabriskie Point — the side looking out over Death Valley — is even more impressive. We see again the Furnace Creek Formation lake sediments, this time with alluvial deposits on top (visible on the right). These materials accumulated in an ancient lake and were lifted up and tilted by the tremendous faulting that formed Death Valley. The pinnacle is called Manly Beacon.


We took advantage of the sunlight and high spirits to take a picture of our Desert Geology 2013 students.


We continued east and then south to Dante’s View, where we looked down into Death Valley from the dizzy heights. In this image we see Telescope Peak towering at 11,049 feet of elevation, while much of the valley floor below is lower than sealevel.

DanteViewFan031013Looking straight down from Dante’s View to Badwater (on the far right), we can see a complete alluvial fan from the narrow channel in the mountain slope to the spreading apron of debris over the salt pan on the valley floor. Badwater Road skirts the periphery of the fan.

After Dante’s View, we continued east and returned to Zzyzx via Death Valley Junction, Shoshone and Baker. Again, I can think of nowhere else one can see so much geological diversity in a single day, from the steamy floor of Death Valley to the heights above where we could walk through patches of snow.

Wooster Geologists return to the Mojave Desert

March 9th, 2013


ZZYZX, CALIFORNIA–It is officially now a Wooster Geology tradition: every other year we take a Spring Break field trip with students, faculty and staff. So far all of our trips have been to the Mojave Desert, for reasons that will be apparent in the following posts. This expedition is the highlight of our Desert Geology course this spring.  This year we have the largest group yet: eleven students, three faculty (Meagen Pollock, Shelley Judge and me — Greg Wiles could not join us because of his leave activities) and two staff (Administrative Coordinator Patrice Reeder and Geological Technician Nick Wiesenberg). We are delighted to also have with us Yoav Avni, a desert geomorphologist with the Geological Survey of Israel (and my good colleague and friend). Four vans of enthusiastic geologists!

We left Wooster very early this morning (5:30 a.m.) to catch a non-stop flight to Las Vegas from Cleveland. After picking up our vehicles at the Las Vegas airport, we drove to the Desert Studies Center (DSC) in delightfully named Zzyzx, California. We’ve stayed here many times before. The station is shown above from the mountain just to its west. Astute observers who visited this little paradise before may notice on the far right side a new solar array to supply electricity to the facility. It is all off the grid and self-contained. It feels in some ways like being on a ship at sea. On the far side of the station you can see the expanse of Soda Lake and some of the mountain ranges in the Mojave National Preserve.

NickKyle030913This year we arrived a bit earlier than usual, so we got a chance to explore the neighborhood around the DSC. Here you can see Nick Wiesenberg and Kyle Burden checking out some nearby outcrops of deformed carbonates (probably the upper part of the Bird Springs Formation, which is Permian in age). This was a chance to break in our boots and stretch our legs before settling into our quarters. The weather is overcast right now, but will dramatically improve tomorrow for the rest of the week.

The weather promises to be excellent for the week we are in the Mojave. All is well as the adventure begins!
