Georgian Bay Geopark thanks Killarney Mountain Lodge for hosting their first ever conference for promotion and development of the Geopark. With the support of Destination Northern Ontario, we had over 30 attendees and many excellent discussions on the deep time story of 2.5 billion years of history. Professor Nick Eyles explained that Georgian Bay has one of the most unique and varied geologies in the world. The Aspiring Georgian Bay Geopark maps crafted with many overlays by James Dobbin revealed that the Georgian Bay Geopark will be one of the largest in the world. Presently, there are over 160 geosites on Georgian Bay, together with educational models and more online at georgianbaygeopark.com. Please fill out our survey. We need to know your thoughts. This is your Georgian Bay Geopark we can’t build it without you!
DEEP TIME’ is the themed expression of how exploring and understanding the past helps create a better future. The unique DEEP TIME story and its eight geological chapters encourages both visitors and residents to know the past, celebrate the present and help create a more resilient future for the Bay and its many communities.
