North America
Drumlins are common in Upstate New York, the lower Connecticut River valley, eastern Massachusetts, the Monadnock Region of New Hampshire, Minnesota, and Wisconsin. Drumlins, which are usually found in swarms or large groups, occur in every Canadian province and territory. Swarms of thousands of drumlins are found in Southern Ontario, Douro-Dummer, Ontario, the Thelon Plan of the Northwest Territories, Alberta, Nunavut and Nova Scotia. The majority of those observed in North America were formed during the Wisconsin glaciation.
The islands of Boston Harbor Islands National Recreation Area are drumlins that became islands when sea levels rose as the glaciers melted.
