The GeologyOntario (includes OGSEarth) web pages will be updated with a new look in the coming weeks, starting at the end of September 2021.
The updated design improves the user experience by simplifying the layout, making the pages more mobile compatible, and aligning with other Ministry web pages.
Please contact Alphons Evers (alphons.evers@ontario.ca) if you encounter any issues after the change or have any questions.
During this update, this page will be removed. Please update your bookmark to the following: Physiography.

Data includes: linear features such as beaches and escarpments, point features such as dunes and mudflow scars, landforms such as drumlins and moraines and physiographic regions.
