18,000 years ago was the last glacial maximum in North America.
The Last Glacial Maximum (LGM) occurred during the final phase of the Pleistocene, about 18,000 years ago. At that time, the world's sea level was more than 400 feet lower than it is today, and glaciers covered about 8% of the earth's surface. 25% of the Earth's land area.
The end of the Glacial Maximum, about 18,000 years ago, is often called the end of the ice age, even though Antarctica and Greenland have vast expanses of ice year-round.
