A Guide to the Ottawa GeoHub
Canada's capital has a remarkably diverse geological and environmental history. Across the Ottawa area, preserved outcrops, geological formations and natural landscapes record an immense span of time—from Precambrian rocks more than a billion years old to deposits, landforms and environments shaped during the last Ice Age just over 11,000 years ago. Together, these features reveal a fascinating geological and environmental record waiting to be explored.
Discover more than a billion years of geological and environmental history
Explore geological and environmental stops and field experiences throughout the Ottawa region, where ancient bedrock, younger sediments, Ice Age landforms and natural environments reveal dramatic changes in the landscape through deep time.
⌕ What to Take
We recommend bringing a hand lens or magnifying glass, hiking boots or sturdy shoes, a camera, notebook and pen, and clothing appropriate for changing weather conditions.
The Geodiversity Education Foundation encourages responsible exploration: take pictures, not samples, and leave your rock hammer at home.
! Safety
When viewing outcrops or geological and environmental features near roads, remain as far from traffic as possible. Avoid climbing unstable outcrops and stay on established paths wherever possible. Visit field sites with at least one other person whenever practical and keep appropriate local emergency contact information available.
