What’s that big rock in your yard, and where did it come from? This course gives participants an understanding of the geologic materials and processes that form the landscapes of the mid-Atlantic region. There is plenty of hands-on study with rocks, minerals and fossils, along with photos, videos and even music, to give participants a real feel for the rocky world around us.
This offering meets for a total of 5 session(s).
