A precise, field-tested guide to Ontario’s ancient shorelines and how they were shaped. This volume reconstructs the water planes of extinct lakes and explains the landscape changes caused by differential uplifts.
In this study, an instrumental survey documents the raised beaches and terraces that marked the shorelines of the extinct Lakes Algonquin and Nipissing in southwestern Ontario. It combines measurements with maps and profiles to reveal how the land tilted and transformed as the lakes faded, offering a clear picture of early 20th-century fieldwork and its interpretations.
What you’ll experience
- Clear explanations of how ancient water planes were identified and measured
- Visuals and descriptions of isobases, profiles, and regional maps
- A historical arc of prior studies and how current findings fit into the broader picture
- Context for the geologic forces that created the current landscape
Ideal for readers of regional geology, physical geography, and the history of lake-level studies.
