To people in the Northeast, scenes like this are the norm.  In this picture of Orient Point, NY, the landscape has been shaped by the receding glaciers of the last ice age, approximately 10,000 years ago.  As the glaciers receded, they left behind all the material that they had picked up along their advancement from the Hudson Bay region.  Imagine a glacier, which is similar to a flowing “river” of ice and snow, being a school bus, and all the rocks and debris seen here were the children picked up along the bus’s route to school.
