Geologic Map of West Virginia. West Virginia's geologic history stretches back into the Precambrian, and includes several periods of mountain building and erosion. At times, much of what is now West Virginia was covered by swamps, marshlands, and shallow seas, accounting for the wide variety of sedimentary rocks found in the state, as well as its wealth of coal and natural gas deposits.
The Ouachita Mountains (/ ˈ w ɒ ʃ ɪ t ɔː /), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America . [ 3 ]
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.

A life-threatening situation unfolded across portions of West Virginia on Thursday morning as powerful thunderstorms moved across the region, leading to numerous reports of flooding, high-water ...
The Ouachita orogeny was a mountain-building event that resulted in the folding and faulting of strata currently exposed in the Ouachita Mountains. The more extensive Ouachita system extends from the current range in Arkansas and Oklahoma southeast to the Black Warrior Basin in Alabama and to the southwest through the Llano , Marathon , and ...
On June 23, 2016, a flood hit areas of the U.S. state of West Virginia and nearby parts of Virginia, resulting in 23 deaths. The flooding was the result of 8 to 10 inches (200 to 250 mm) of rain falling over a period of 12 hours, resulting in a flood that was among the deadliest in West Virginia history. [ 3 ]
Although formidable, a look at the topography reveals a discontinuous series of mountain ranges with distinct geological origins. [12] The rocks making up the mountains were formed before the mountains were raised. The cores of the mountain ranges are in most places formed of pieces of continental crust that are over one billion years old.
Lake Ouachita has rare jellyfish (non-stinging) and sponges found in very few freshwater lakes. Scuba divers from all over the world enjoy the underwater experience as well as the special spear fishing season. The original purpose of Lake Ouachita was flood control and hydroelectricity. One feature by the Corps of Engineers is the Geo-Float ...
