When was Long Island formed?
70 million years ago
Pre-glacial geologic events in the Long Island include the formation of the ancient (over 400 million year old) metamorphic bedrock that forms the foundation upon which Long Island rests, and the deposition of sands and clays on this bedrock 70 million years ago, during the late Cretaceous period.
Is Long Island a glacial moraine?
Long Island, as part of the Outer Lands region, is formed largely of four spines of glacial moraine, with a large, sandy outwash plain towards its barrier islands and the Atlantic Ocean.The land to the south of this moraine to the South Shore is the outwash plain of the last glacier.
When was New York covered in ice?
In New York, the ice that covered Manhattan was about 2,000 feet high before it began to melt in about 16,000 BC. The ice in the area disappeared around 10,000 BC. The ground in the New York area has since risen by more than 150 ft because of the removal of the enormous weight of the melted ice.
How many years ago did the first glacier impact Long Island?
By the time the glacier covered the northern half of Long Island, about 22,000 years ago, its edge was melting as fast as new ice was pushing down from Canada.

What glacial formation exists between Staten Island and Long Island?
New York’s Glacial Landscape

Glaciers in New York City – Alley Pond Park
The landscape itself, however, came into existence roughly 15,000 years ago, during the Pleistocene Epoch, when a passing glacier carved out the landscape of New York City. The land beneath this park formed during the last ice age, which began around 1.5 million years ago.
How far did the ice age reach in North America?
Laurentide Ice Sheet, principal glacial cover of North America during the Pleistocene Epoch (about 2,600,000 to 11,700 years ago). At its maximum extent it spread as far south as latitude 37° N and covered an area of more than 13,000,000 square km (5,000,000 square miles).
Why are there no glaciers in New York?
The reason that no glaciers exist today in New York State is that there are no places where the snow does not completely melt before the following winter. Snow and ice exist as crystals. When snow falls,the flakes are usually light and feathery.Glaciers do not flow because the ice is melting.
