The Atlantic Northeast, Natural Features

Maine coastline, clear lakes, ice sheets, deciduous trees, Natural forces

Natural forces have contributed greatly to the present-day geography of this region. For example, mountains and hills consisting of hard crystalline rock were scoured by ice sheets that receded from the region 10,000 years ago. When the ice receded, it left thin soils and an undulating surface favorable for fast-running streams and bright, clear lakes. In Vermont, the rounded summits of the Green Mountains are more pronounced in slope, reaching elevations of nearly 1,900 m (6,300 ft). The Maine coastline is rugged and deeply indented with river channels that are often flooded by the sea.

The landscape is covered with a relatively dense mixed forest of coniferous and deciduous trees. The original trees were cut down for lumber, shipbuilding, and fuel, or were cleared for agriculture. Virtually all of the remaining trees are second-growth. Second-growth trees are usually a less desirable variety because they produce less wood and wood of a lower quality than old-growth trees.
