Dave West is a North Carolina native who completed his Ph.D. in Geological Sciences at the University of Maine in 1993. Prior to arriving at Middlebury in 2001, Dave taught geology Bowdoin, Lafayette, and Earlham Colleges.
Broadly speaking, Dave’s research is focused on understanding the distribution, in time and space, of deformational and thermal events during mountain building processes. Dave is basically a “hard-rock field geologist” whose research involves bedrock geologic mapping, structural analysis, igneous and metamorphic petrology, and thermochronology. Most of his research to date has been directed towards unraveling the ancient plate tectonic history of the northern Appalachian mountains.

Geologic Evolution of Vermont
Course Description
Geologic Evolution of Vermont
This course explores the fascinating geology of Vermont. Students learn the geology through six field problems, involving extended trips around western Vermont. Lectures on the meaning of rocks support the fieldwork. The last few indoor labs are devoted to understanding the geologic map of Vermont. Emphasis is on descriptive writing and on use of data to interpret origin of rocks. Culminates in a written report on the geologic and plate tectonic evolution of Vermont. (One ECSC course) 3 hrs. lect., 3 hrs. lab/field trips (formerly GEOL 0201)

Requirements
ECSC 0311
Mineralogy (formerly GEOL0211)
Course Description
Mineralogy (formerly GEOL 0211)
This course covers the nature, identification, composition, and meaning of minerals and mineral assemblages. Introduction to crystallography, hand-specimen identification, optical mineralogy, x-ray analysis, and electron microbeam analysis. Laboratory: study of minerals in hand-specimen and under the polarizing microscope; use of x-ray diffraction and electron microscopy in mineral analysis.

Course Description
Senior Thesis Research
Upon completion of ECSC 0400, all senior geology majors will continue their independent senior thesis research by taking one unit of ECSC 0700. This research will culminate in a written thesis which must be orally defended. (Approval only) (formerly GEOL 0700)

Earth Resources
Course Description
Earth Resources: Origin, Use, and Environmental Impacts
The global economy world politics, and many aspects of our daily lives are dependent on the extraction and use of materials taken from the Earth. Unfortunately, within our lifetimes, we will be faced with significant shortages of many of these resources. In this course we will focus on how resources such as oil, coal, aluminum, and even gem minerals are generated by geological processes, how they are extracted and processed, and how these activities impact the environment. Several field trips will allow us to view first-hand the impacts of resource extraction and use in the local area. 3 hrs. sem.

Natural Hazards
Course Description
Natural Hazards
Despite increasing technological sophistication, modern civilization remains vulnerable to natural hazards such as earthquakes, volcanic eruptions, tsunamis, flooding, landslides, extraterrestrial impacts, and other events. In this course we will consider the geologic mechanisms behind these hazards, the societal implications of these hazards, and approaches to reducing risk. Case studies will be combined with exploration of fundamental geologic concepts to provide students a foundation for understanding risk exposure and evaluating approaches to hazard management. (Not open to students who have taken GEOL 0112 or 0170) 3 hrs. lect./1 hr. disc.

Structural Geology
Course Description
Structural Geology
Plate tectonics and mountain building processes result in deformation of the Earth's crust. Structural geology is the study of this deformation, and this course will examine the many types of structures found in crustal rocks (folds, faults, etc.) and explore the forces responsible for their formation. Laboratory exercises will emphasize the hands-on description and analysis of structures in the field, as well as the practical aspects of map interpretation and computer analysis of structural data. (GEOL 0112, or GEOL 0161, or GEOL 0170 or by waiver) 3 hrs. lect., 3 hrs. lab/field trips

Energy Resources
Course Description
Energy Resources: Geological Origins and Environmental Impacts
In this course we will discuss how different types of energy resources are formed by geological processes, how they are extracted and used, and how these activities impact the Earth’s environment. We will discuss traditional fossil fuels such as oil, coal, and natural gas, as well as nuclear, wind, and solar power. A portion of the class will focus on major energy issues facing the northeastern United States, such as the role of nuclear power in Vermont, hydraulic fracturing (“fracking”) for natural gas in New York and Pennsylvania, and the wide spread installation of wind turbines and solar farms. (Not open to students who have taken FYSE 1120)
