Kame
Sabrina Womer
Twenty thousand years ago the ice age formed glaciers and left big boulders. On the Colville Indian Reservation on Highway 155 there is a kame. A kame is formed by a lake on top of a glacier.
The glacier left sediment that had formed several mounds around Washington but as a result most of them have gotten washed out and some are still standing to show you actually how big the glaciers were.
During the ice age glaciers were formed and when the glacier began to melt, there were rivers formed on either the top, bottom , or the middle of the glacier. That sediment from the melting glacial river can be seen as hills that look like snakes.
