Seminar Lab Subject:
Ongoing Geological and Archaeological Investigations at the Pedersen Site in SW Minnesota
Seminar Lab Location :
In-person only at U of Minnesota Keller Hall Room 3-230
Address: 200 Union St. SE, Minneapolis MN (parking ramp is next door)
Lecture start time 7:00 PM CT
Seminar Lab Details:
Summary:The Pedersen site is an island site in southwestern Minnesota with one of our state’s richest and longest records of human occupation extending back in time 10,000 years or more. The site was studied in the 1950s and 1970s, and now almost 50 years later a joint partnership between the Science Museum of Minnesota and the University of Minnesota has brought together an interdisciplinary team of researchers and collections professionals to re-examine this important site. This talk will explore what we’ve learned about the site, its geological and environmental setting, as well as what we still hope to discover.
Biography:PhD, 2005, University of California, Berkeley. My research uses a combination of geophysical approaches (e.g., rock magnetism, paleomagnetism, gravity), material characterization techniques (e.g., scanning and transmission electron microscopy, scanning force microscopy, X-ray diffraction), and field geology methods to critically examine a broad range of scientific problems. These tools enable my group to collaborate with specialists from a variety of disciplines, including the geosciences, anthropology, soil science, planetary geology, material sciences, physics, chemistry, and biology. Our research aims to understand the fine details of processes that operate on global, tectonic, outcrop, and nanometer scales.

Seminar Lab Subject:
Saturday Lab: Rock Cycle (Hand-identification)
Seminar Lab Location :
Lab time is 10:00 AM to 12:00 PM (We suggest arriving at 9:45. The doors are card-access only; someone will be stationed at the south door (at least) to allow participants in.)
Macalester College Geology Dept., SW area of basement of Olin-Rice Science Center (Building 14), (south end of campus, by tennis courts)
Abstract: A hand-on lab during which participants will examine the various members of the rock cycle and learn to distinguish each type based on texture and composition. With careful examination, constituent minerals and textures in rocks can be identified facilitating proper classification. Once correctly identified, each rock's 'story' can be read allowing interpretations of emplacement or eruption, environments of deposition, pressure and temperature conditions, and ultimately, the tectonic setting where each rock was formed. With basic identification skills honed, hopefully participants will be able to predict expected changes in specific rocks as they travel through the rock cycle.
Biography: Jeff Thole is the Geology Laboratory Supervisor at Macalester College. He teaches laboratory sections of the Introductory Geology courses and runs the Keck Laboratory which includes a X-ray diffractometer, a micro-XRF (x-ray spectrometer), a low vacuum scanning electron microscope with EDS and WDS X-ray spectrometers, a gamma-ray spectrometer and an atomic-force microscope. Jeff graduated from the University of Minnesota - Duluth and worked for the US Geological Survey in Reston, Virginia, before obtaining a M.Sc. in Geology at Washington State University. He worked as an environmental consultant for 5 years before joining Macalester College in 1996.

Seminar Lab Details:
Abstract: Southern Idaho’s Snake River Plain (SRP) is a volcanic wonderland. Initially forged by its passage over the Yellowstone hot spot, the SRP records a variety of eruptive styles and volcanic landforms that formed over the past 12 million years. Ranging from explosive, caldera-forming eruptions of ash and searing pyroclastic flows to benign, effusive eruptions of basaltic lava, the region hosts both classic and less obvious types of volcanoes. With its arid climate and youthful volcanism, the SRP’s volcanic landscape is relatively pristine and inviting to exploration and observation. Join College of Southern Idaho geology professor and author Shawn Willsey as he guides you though this region’s fascinating geologic history as well as some of its most impressive volcanic features.
Biography: Shawn Willsey is a Distinguished Professor of Geology at the College of Southern Idaho where he has taught since 2004. He earned a BS in Geology from Weber State University and an MS in Geology from Northern Arizona University. Shawn is the author of Geology Underfoot in Southern Idaho and co-author of Roadside Geology of Idaho. He maintains a popular YouTube channel where he posts field-based geology videos. Shawn is a licensed professional geologist in Idaho and has led geologic field trips for various groups throughout the intermountain West as well as Iceland, Hawai’i, and Scotland. In addition to geology, Shawn also teaches whitewater rafting and rock climbing courses at CSI and is a licensed whitewater and climbing guide. He lives in Twin Falls with his family.
