A fieldtrip to nearly a 1000 ft below can be an interesting one to say the least. Drs. Johnson and Rohs lead the trip including stops at the Brushy Creek mine and igneous rocks at Tiemann Shut-Ins in southeast Missouri. The students in these classes were able to go down into an active lead mine to see galena, sphalerite, and chalcopyrite mineralization in Cambrian-aged dolomitic limestones.

Knob Lick lookout point exposes the Grassy Mountain ignimbrite and intrusions of the Butler Hill granite and well as providing a view of the huge volcanic caldera that had active eruptions over 1.4 billion years ago. |
Elephant Rocks State Park, about 1 hour south of St. Louis, MO exposes the Graniteville granite, commonly known as Missouri “Red” where differential weathering produces rounded, boulder-sized. |
