GLACIERS COVERED YOUR
NEIGHBORHOOD FOR 75,000 YEARS
THIS IS LONG ISLAND
Glaciers are giant walls of ice that get bigger and bigger. Then one day they melt. When they're growing they plow through mountains like a monster bulldozer. When they melt they leave behind hills, lakes, rich soil for plants and good land for animals and birds.
This is what Long Island looked like 20,000 years ago. Locked inside the glacier are hundreds of feet of rocks and gravel. When the glacier melted it left that material behind. When you travel around Long Island try and picture 300 feet of ice and rock above your head, suspended like in an ice cube. The hills, flat areas, ponds, lakes and ravines were all deposited or carved from the glacier's actions when it was either growing or melting.
YOUR NEIGHBORHOOD LOOKED LIKE THIS 18,000 YEARS AGO!
Exciting, funny video watch as glacial walls collapse!
AFTER THE GLACIERS MELTED, PINE FORESTS GREW ATTRACTING DEER AND OTHER WILDLIFE.
YOUR NEIGHBORHOOD LOOKED LIKE THIS 12,000 YEARS AGO
When the climate became warmer and Native People arrived on the land they found fresh water, hills to shelter from the wind, birds, animals and fish. The land's bounty upon which people depended was made possible by the after effects of the glacier's retreat.
YOUR NEIGHBORHOOD LOOKED
LIKE THIS 7,000 YEARS AGO
Long Island's history begins with the glaciers. They left us with rich farmland, hills, ravines, beaches, fresh water, bays, marshes, ponds and lakes. The jagged coastline in the maps below shows the relationship of massive earth forces with the terrain we all walk today.
Glacial hills (moraine)
The map above shows how resources follow the geology. Native People understood how to use those resources to create a successful life.Certain species of animals, fish and plants favor specific habitats. The sacred sites are located on hilltops or islands, also a remnant of the glacial retreat.
