Len Eisenberg, past president of The Jefferson Center, will lead a tour through geologic time at the Briscoe Geology Park, 265 N Main St, Ashland on Sunday May 11 at 4pm. Bring your questions and comments for the many issues, both ancient and modern, connected to study of earth and life history. Briscoe Geology Park contains three 'time walks' along with visitors and students discover local geology, and how life and our planet have changed through time. Adventurous souls can try their hand at a grade 6 to 8 activity sheet, the same as students attempt to complete when they come to the park on field trips. More about the park can be found at http://ashland.or.us/Page.asp?NavID=14136. Please note we will meet at the Park and then gather for refreshments and discussion following the presentation in Len's studio inside the old Briscoe Elementary School.
