Workshops Presented for Naturalists
Bob Vaiden presented two 3-hour workshops on March 25, 2009, that included PowerPoint presentations. The first workshop was for the Cook County Master Naturalist program; the second workshop was for the Kankakee County Master Naturalist program. In both workshops, Vaiden presented basic stratigraphic principles, Illinois geologic history ("Build Illinois"), weathering, soil, and the effect of geology and geomorphology on the landscape and ecological communities. Additionally, Vaiden worked with the Anita Purves Nature Center in Urbana on a new exhibit and arranged for the Center to acquire a surplus sieve. He answered a request concerning a rock specimen by e-mailing the explanation that included Web links with photos.
