All of Bedford County lies far to the south of the terminal moraine, and thus it was never glaciated (PA Geological Survey Map 59). However, during the Pleistocene epoch, or "Ice Age," periglacial (meaning "around glacier" or simply "cold") processes dominated. Most of the county was most likely a tundra at that time. The many boulder fields ...
Map showing general location of the Bedford Shale in Ohio, northeastern Kentucky, and western Pennsylvania. The Bedford Shale in Ohio has been extensively studied since 1943, [23] and the 1954 study by Pepper, de Witt, and Demarest was still considered the classic study of the formation as late as 1991. [24]
Bedford County was created on March 9, 1771, from part of Cumberland County and named in honor of Fort Bedford. The 1767 Mason–Dixon line had stabilized the southern border with Maryland. In the aftermath of the American Revolution , the population increased largely due to emigration.
Chestnut Ridge is an elongate hill trending northeast-southwest in west-central Bedford County, Pennsylvania. It is partially forested with rural homes, farms, and notably apple orchards. Four small towns surround it: Schellsburg, New Paris, Fishertown, and Pleasantville.
Ohio produces three billion dollars worth of natural gas and $844 million of oil annually. Coal deposits were first recognized in the 1740s by early settlers and were mapped as early as 1752. Decreased demand due to increased natural gas production has reduced coal mining in the 2010s, although one underground mine and three surface mines ...
The Hamilton Group is a Devonian-age geological group which is located in the Appalachian region of the United States.It is present in New York, Pennsylvania, Maryland, Ohio, West Virginia, northwestern Virginia and Ontario, Canada, [1] [2] and is mainly composed of marine shale with some sandstone.
The Glenshaw Formation is a mapped sedimentary bedrock unit in Pennsylvania, Maryland, West Virginia, and Ohio, of Pennsylvanian age. It is the lower of two formations in the Conemaugh Group, the upper being the Casselman Formation. The boundary between these two units is the top of the marine Ames Limestone. [2]
Berea Sandstone was formed in the Late Devonian period. [10] [11] Prior to the 1970s, it was assigned a Mississippian age. [10]The Devonian-Carboniferous boundary was realigned based on research from Europe, but various geologists were not aware of the changes and so incorrectly assigned Berea Sandstone to the Kinderhookian (early Mississippian).
