PHYSICAL MAP

Cumberland County Topographic Map

Cumberland County features a mix of coastal plains and low hills. While the interior has wooded rises, the shoreline remains mostly flat. Rocky ridges appear unexpectedly in some areas, though they never become too steep. Even near the ocean, small cliffs occasionally interrupt the gentle slopes.

The coast immediately stands out, with jagged inlets and scattered islands. Portland’s urban sprawl appears as gray grids near the shore. Inland, forests and lakes create dark green and blue patches. Sebago Lake, for example, is enormous. Narrow roads weave through the trees, connecting small towns across the county.
