How far south did the most recent major ice age in North America extend?

The most recent major ice age in North America, known as the Last Glacial Maximum, occurred around 20,000 years ago. During this period, ice sheets extended as far south as the northern United States, reaching into areas like the Great Lakes, parts of the Midwest, and even down to the northern regions of present-day Pennsylvania, Ohio, and Indiana. In some places, glaciers also reached into the northern parts of New England. However, the ice did not extend as far south as the central or southern United States.
