The Glaciated Allegheny Hills ecoregion is a continuation of the Unglaciated High Allegheny Plateau (62d) to the south, but it has a more rounded topography and a higher density of lakes because it was glaciated during the Pleistocene Epoch. The higher elevations are created by resistant Devonian-age strata of sandstone and shale. The Glaciated Allegheny Hills ecoregion is deeply dissected; soils are stony, acidic, low in fertility, and often found on steep slopes. The west side of the region experiences high lake-effect precipitation. The soil, climate, and rugged topography make the region more suited to tree growth than agriculture. Hardwood forests, particularly northern hardwoods, predominate, although some Appalachian oak forest also occurs on dry or south-facing slopes.
