But a few major rivers, such as the Delaware River, the Susquehanna River, and the Potomac River are evidently older than the present mountains, having cut water gaps that are perpendicular to hard strata ridges.
The evidence point to a wearing down of the entire region (the original mountains) to a low level with little relief, so that major rivers were flowing in unconsolodated sediments that were unaffected by the underlying rock structure.

Parallelism of mountain ridges and intervening valleys is thus attributable to the folding of the rocks, but the origin of the interior structure of the mountains is to be kept distinct from the origin of the mountains as features of See also:
English colonies; the continuity of the system, the bewildering multiplicity of its succeeding ridges, the tortuous courses and roughness of its transverse passes, a heavy forest and dense undergrowth all conspired to hold the settlers on the seaward-sloping plateaus and coastal plains.

 Songcatcher The Overview
The Appalachian mountains, which stretch down the eastern coast of North America from Newfoundland to Georgia, are soft, rounded, heavily eroded mountains with the appearance of lush, undulating green hills separated by hidden valleys or "hollers." Most of the mountain territory is forested swampland, covered in ferns and mosses.
This tale of unexpected romance takes audiences into the rarely seen Appalachian mountains where on the rickety porches of banjo-picker's cabins and subsistence farmer's shacks the everyday music of the people - music filled with storytelling, protest, politics, history, romance and sheer celebration -- was born.

Some of the Southern Appalachian mountain summits are bare of trees, exhibiting characteristics of grassy balds and heath balds.
There is no timber line in the Southern Appalachians, but cool climate and high winds at the mountain summits as well as anthropogenic influences such as grazing have maintained the balds, although the historical explanation for these anomalies in the forest is unknown.

The Southern Appalachians are also a global hotspot for aquatic species, in part because they drain to the south and, unlike the major European rivers that flow northwards, allow species to escape ice-age extermination.
Assemblages of contemporary vegetation in the Appalachians are strongly influenced by elevation and moisture (Whittaker 1956), but soils and history, including disturbances and pathogens, have also shaped their composition.
While the Southern Appalachians lack the tree line found in the north, they have scattered tree-less balds, which are being invaded by heaths dominated by Catawba rhododendron (Rhododendron catawbiense) and mountain laurel (Kalmia latifolia).

 Appalachian Mountains
Instead, the Appalachians are roughly equal in height to mountains few have heard of, such as the Yablonovy Range of eastern Siberia (high point of 8862') or the Mtumba Range in Malawi, Africa (high point of 8071').
There are a few places in the Appalachians not covered with trees: the high peaks of the Northern Appalachians, where the combination of both high altitude and latitude keeps a few small and widely scattered areas above timberline, and "Balds" in the south where, mysteriously, huge open meadows cover summits that should be forested.
The Southern Appalachians are often said to begin south of the Potomac River, and the Central Appalachians could be defined as those of New York and Pennsylvania.

 Appalachian Mountains, Carbon Dioxide Caused Long-Ago Global Cooling
PHILADELPHIA — The rise of the Appalachian Mountains may have caused a major ice age approximately 450 million years ago, an Ohio State University study has found.
The weathering of the mountains pulled carbon dioxide (CO2) from the atmosphere, causing the opposite of a greenhouse effect -- an "icehouse" effect.
According to the Ohio State study, most of the Appalachian weathering took place over 7 or 8 million years -- a very short time, by geological standards -- as the climate moved from one extreme to the next.

 The Appalachian Mountains
The Appalachians are among the oldest mountains on Earth, born of powerful upheavals within the terrestrial crust and sculpted by the ceaseless action of water upon the surface.
When the mountains were thrust up, blocking their westward course to the ancient sea that once covered the American Midwest, these old rivers cut out their own routes, creating those spectacular canyons, gorges, and “narrows” that are part of Appalachian scenery.
The ruggedness of the Appalachians, the transverse ranges by which they are crossed, their maze of streams and rivers, and their lack of natural passes created a formidable barrier to early explorers and settlers.

 A Precipitation and Flood Climatology of the Southern Appalachian Mountains   (Site not responding. Last check: 2007-10-07)
Although surface winds are generally variable throughout the year across the southern Appalachian Mountains, low level southerly winds normally develop across the southern Appalachian region in association with synoptic-scale systems, bringing abundant moisture from the Gulf of Mexico and the Atlantic Ocean.
Flash flood reports across the southern Appalachian Mountains exhibit the typical statistical biases: reports have increased recently due to the increase in spotter and verification efforts of the National Weather Service; and reports are skewed toward the populated counties of the region.
August was found to be the most active month in terms of flash flooding across the southern Appalachian Mountains, but flash flooding is a problem throughout the entire year mainly due to the steep topography characteristics of the southern Appalachian Mountains and their proximity to the Gulf of Mexico and Atlantic Ocean moisture source regions.
