Geological events that happened in this area have mostly to do with glaciers and the ice age. Thousands of years ago there was ice covering the New England states and all the way down to Indiana. Eventually all the ice melted and formed rivers and lakes in that area. Some animals found in this biome are deer, gray squirrels, mice, raccoons, salamanders, snakes, robins ,frogs, and many kinds of insects. In the winter, most of these animals migrate to the south.
