Viewing Our Home Through Geology-Tinted Glasses

Untitled drawing.png

Much of our region was born of fire. Not forest fire, but fire from inside the Earth.

Volcanoes had much to do with shaping the landscape we love and live in, and geologists can tell you the whole story. And will, if you give Karen Grove some time.

Grove teaches adult classes on geology through OLLI at Southern Oregon University.

We bring her in for a brief lesson in the sculpting of our region over billions of years.
