Research:

My research and teaching interests include all aspects of igneous petrology and volcanology. Since coming to Western my students and I have had many projects on the igneous rocks of the Gunnison Basin. These projects include:

• the petrology and geochemistry of the old Precambrian island arc exposed south of town;
• petrology and volcanic structures in the large Oligocene ash flow sheets from the San Juans exposed around Blue Mesa Reservoir;
• petrology and volcanology of West Elk Volcano;
• petrology and geochemistry of the Gunnison Laccolith cluster that makes up the high peaks north of town, including Crested Butte;
• petrology and geochemistry of the Miocene flood basalts that makeup Flat Top, Red Mountain, Grand Mesa etc.;

• petrology and geochemistry of the post ash-flow (Hinsdale) shoshonite and latite lavas exposed on the north slope of the San Juan volcanic field.
• petrology and geochemistry of Tomichi Dome.

Virtual Field Trip:

• Ash statigraphy at East Elk Creek.

Recent Research:

• Geologic Map of the McIntosh Mt. Quadrangle
• Geologic Map of the Little Soap Park Quadrangle
• Geologic Map of the Almont Quadrangle
• Geologic Map of the Gunnison Quadrangle
• Geologic Map of the Signal Peak Quadrangle
