The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago. The first mountain range in the region was created when the continents of Laurentia and Amazonia collided, creating a supercontinent called Rodinia. The collision of these continents caused the rocks to be folded and faulted, creating ...
Continental collisions raised the Appalachian-Ouachita chain to a lofty mountain range on the scale of the present-day Himalayas. The massive bulk of Pangea was completed near the end of the Paleozoic era (the Permian period) when Africa plowed into the continental agglomeration, with the Appalachian-Ouachita mountains near the middle.

The first cartographic appearance of Apalchen is on Diego Gutiérrez's 1562 map; the first use for the mountain range is the 1565 map by Jacques le Moyne de Morgues. [16] Le Moyne was also the first European to apply "Apalachen" specifically to a mountain range as opposed to a village, native tribe, or a southeastern region of North America. [17]
The Great Appalachian Valley, also called The Great Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trough, including a chain of valley lowlands, and the central feature of the Appalachian Mountains system.
The following is a list of subranges within the Appalachian Mountains, a mountain range stretching ~2,050 miles from Newfoundland and Labrador, Canada to Alabama, US. The Appalachians, at their initial formation, were a part of the larger Central Pangean Mountains along with the Scottish Highlands , the Ouachita Mountains , and the Anti-Atlas ...
Paleo-Indian cultures were the earliest in North America, with a presence in the Great Plains and Great Lakes areas from about 12,000 BCE to around 8,000 BCE. [citation needed] Prior to European settlement, Iroquoian people lived around Lakes Erie and Ontario, [2] Algonquian peoples around most of the rest, and a variety of other indigenous nation-peoples including the Menominee, Ojibwa ...
Blue Ridge Mountains - Front Royal, Virginia Although the term "Blue Ridge" is sometimes applied exclusively to the eastern edge or front range of the Appalachian Mountains, the geological definition of the Blue Ridge province extends westward to the Ridge and Valley area, encompassing the Great Smoky Mountains, the Great Balsams, the Roans, the Blacks, and other mountain ranges.
There are over 200 named lakes, with the number of smaller lakes, ponds, and other bodies of water reaching over 3,000. The region has over 1,200 miles of river. [5] The current relief owes much to glaciation. Among the named lakes around the mountains, are Lake George, Lake Placid, and Lake Tear of the Clouds, which is the source of the Hudson ...
