The Making of Canada: Four Billion Years of Earth History with Dr. Nick Eyles
March 11, 2010 @ 7:00 pm
This talk will summarize the long geological evolution of Canada. It is an immigrant country made up largely of far-traveled crust brought together by plate tectonics. Its history begins 4.1 billion years ago with a small landmass (preserved as the Slave craton in the present day Northwest territories) and ends with glaciations of the last 2 million years which have profoundly shaped the landscape. Knowledge of Canada’s geologic history is key to understanding many modern environmental issues. The Annual General Meeting will follow this presentation.
OSFN Indoor Meetings are normally held on the second Thursday of the month at 7:00 p.m. at the Bayshore Community Centre, 1900 3rd Ave E Owen Sound. There are no Indoor Meetings in July and August. Please see the individual event listings below for more details.
We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club activities, club business, social time, nature sightings and reports.
The club also offers a full schedule of outdoor activities during the year. Through these outings, members learn more about the birds, plants, mammals and geology of this part of Ontario. We also keep a protective eye on our precious natural areas.
