There are many ways to participate in Geoheritage Day! Visit exceptional geological sites in the National Capital Region and across Canada, virtually, in person on your own, or you can join us for our annual live event, held each fall in Ottawa/Gatineau.
This annual event, run on a Saturday in late September or early October, aims to bring people outdoors to visit some exceptional Geosites in the Ottawa region and learn how geological processes have shaped, and continue to shape our local landscape. Expert volunteers host selected sites from 10:00am to 3:00pm to help visitors learn about geological features that can be seen at the site.
