Ice Age
- Many landforms in New York were formed long before people lived there.
- Scientists believe that Earth had several period of very cold weather
- Such a period is known as an Ice Age
Glaciers
- The most recent Ice Age probably ended about 10,000 years ago
- During that Ice Age, a huge glacier, or thick sheet of ice, moved across
most of New York
New York’s Glacier
- New York’s glacier moved like a giant bulldozer, pushing tons of soil and
rock along its path
- The glacier crawled as far south as Long Island
- A line of low hills, called moraines, marks where the glacier stopped
Allegany State Park
- Allegany State Park found in southwestern New York is the only part
which was not covered by the glacier
- Here the steep valleys and pointed hills look different from the land
outside the park
The Ice Age Ends
- Earth warmed up about 10,000 years ago
- Water from melting glaciers filled many deep holes dug by the glacier’s
rough rocks and created lakes such as Oneida Lake
- As the ice melted, the glacier dropped soil and rocks it had picked up
- The mix of soil and rocks is called till
- Drumlins, smoothly rounded hills, were formed by the melting glacier
