Greetings! I am the Earth Systems Science Adjunct Instructor here at beautiful Treasure Valley Community College. Before joining the Science Team at TVCC, I was a visiting instructor at University of Wisconsin-Eau Claire (2013-2015). I also teach sections GEOL 406 Geology Field Camp in Central Oregon and Southwest Montana for University of Oregon.

Please email me (scastonguay@tvcc.cc) for more information regarding the courses listed. I am THRILLED to share my knowledge of the Earth and welcome you to any of my courses to learn the Big Ideas of Earth Systems Science.

Community Engagement:
The Western Treasure Valley Magazine, published by the Argus-Observer, wrote me into their "Why I love the Western Treasure Valley" segment in Spring 2018.

In spring 2017, I was interviewed on the Oregon Public Broadcasting radio show "Think Out Loud" while they were in the region.

I participate as an Attending, Board, or Committee member in several organizations:
Friends of the Owyhee (conservation and education)
EUVALCREE (equity, inclusion, and society)
Kiwanis International (Serving the needs of Children worldwide)
CascadiaNow! (Bioregionalism)

Other local press.

Professionally  I’m an active member of the Geologic Society of America, the Society of Economic Geologists, and the National Association of Geoscience Teachers which enable me to attend conferences and workshops, stay current on new research, and collaborate with Earth Systems scientists across the world. My research is focused in Structural Geology and Neotectonics, looking the deformation of Earths surface. I’ve had projects in Death Valley (M.Sc. Thesis), Central Oregon, and Northern Wisconsin, and now focus my inquiries on the Owyhee Plateau and the Western Treasure Valley. I'm also very interested in Geoscience Education, fungi-silicate interactions, the interactions of the Earth Systems and the Anthropocene. 

Personally, I was raised on a cattle ranch in western South Dakota where my love for the landscape began. I have fond memories of riding horseback through wooded draws pondering the origin of the surrounding buttes and their layered appearance. When I was in grade school, the most complete T. rex skeleton discovered to-date, Sue, was excavated 40 miles north of my hometown. After taking some time off after High School, I started my higher education at Lane Community College where I attended my first geology course. My college undergraduate studies in geology led me to some amazing locations for ‘work’, such as central Alaska, southern California, northern Mexico and northeastern Oregon.

My family and I enjoy hiking, biking, gardening, mushroom hunting, and Pokémon.
