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 river's path traveled through modern-day West Virginia, Kentucky, Ohio, Indiana, and Illinois, finally emptying into the Gulf of Mexico, which at the time extended to southern Illinois. The glaciers of the Ice Age soon began to block the Teays, effectively damming the river and forming Lake Tight, near what is now Chillicothe, Ohio.
Lake Monongahela was a proglacial lake in western Pennsylvania, West Virginia, and Ohio.It formed during the Pre-Illinoian ice epoch when the retreat of the ice sheet northwards blocked the drainage of these valleys to the north.
West Virginia was never the site of glacial activity during the Ice Age, but the state was home to creatures like mammoths, mastodons, and giant ground sloths. One local ground sloth, Megalonyx jeffersonii , was subject to the scholarly investigations of Thomas Jefferson , who misinterpreted the large-clawed remains as belonging to a lion-like ...
In Virginia and West Virginia, the Teays River flowed in the valleys of the modern New River and Kanawha River (Hansen, 1995). The river then flowed west to Scioto County, Ohio, and to Ross County, Ohio, near Chillicothe. The valley then disappears under glacial sediments but can be tracked using water well yields and other means (Hansen, 1995).
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
Glaciation in this area of the plateau removed the sharp relief that is seen in the plateau's unglaciated areas. The line of the distant peaks approximates the level of a peneplain that was uplifted to form the plateau. Aerial view of Allegheny Plateau terrain surrounding Weston, West Virginia
Ice Mountain was also detailed in Hu Maxwell and Howard Llewellyn Swisher's History of Hampshire County, West Virginia: From Its Earliest Settlement to the Present (1897), O. F. Morton's History of Hampshire County (1910), and Homer Floyd Fansler's "Ice Mountain: Nature's Deep Freeze" in the July 1959 issue of West Virginia Conservation. [6]
