The Laurentide Ice Sheet
The Laurentide Ice Sheet was the last major glacier to cover North America (The Retreat Chronology of the Laurentide Ice Sheet). It was responsible for shaping much of New England into what we know it as today (New England Geology).

The Laurentide Ice Sheet was the largest glacier in North America during the last ice age (The Retreat Chronology of the Laurentide Ice Sheet). Forming around 75,000 years ago (Laurentide Glaciation of the Massachusetts Coast), the Laurentide Ice Sheet covered much of Canada and part of the US. At some places, the Ice Sheet was 4 km thick. The Ice Sheet reached its maximum size around 20,000 years ago. From that point, it began to retreat (The Retreat Chronology of the Laurentide Ice Sheet). The terminal moraine that formed from the Laurentide Ice Sheet is now visible in Long island, Martha's Vineyard, Nantucket, and parts of Cape Cod (New England Geology). The retreat was triggered by increasingly hot summers in the beginning of the Holocene epoch (Nature.com).
