Recent ice age in north America?

The most recent ice age in North America was the Wisconsin glaciation, which began about 75,000 years ago and ended about 10,000 years ago. During this time, glaciers covered large parts of Canada and the northern United States, as well as parts of Alaska and the Pacific Northwest. The Wisconsin glaciation was the last of a series of ice ages that have occurred throughout Earth's history, and it is thought to have been caused by a combination of factors, including changes in the Earth's orbit and climate, as well as volcanic activity.
