}}Bedford County is a county located in the U.S. state of Pennsylvania. As of the 2010 census, the population was 49,762.[2] The county seat is Bedford.[3]

History

In 1750 Robert MacRay, a Scots-Irish immigrant, opened the first trading post in Raystown (which is now Bedford) on the land that is now Bedford County. The early Anglo-American settlers had a difficult time dealing with raids from Native Americans. In 1754 fierce fighting erupted as Native Americans became allied with the British or French in the North American front, known as the French and Indian War, of the Seven Years' War between those nations in Europe.

In 1759, after the capture of Fort Duquesne in Allegheny County, on the Allegheny and Monongahela rivers, English colonists built a road between the fort (which was renamed as Fort Pitt) to the newly built Fort Bedford in Raystown. The English defeated the French in the war and took over their territories in North America east of the Mississippi River. Treaties with the Indians opened more land for future peaceful settlement.

This road followed and improved on ancient Indian trails. In later years it was widened and paved as "Forbes Road"; it is now Route 30. When the Pennsylvania Turnpike was built, this interstate toll road became the main highway through Bedford County.

Bedford County was created on 9 March 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. Within a lifetime Old Bedford County was greatly reduced from its original boundaries. Huntingdon County was created on 20 September 1787, mainly from the north part of Bedford County, plus an addition of territory on the east (Big Valley, Tuscarora Valley) from Cumberland County. Somerset County was created from part of Bedford County on 17 April 1795. Centre was created on 13 February 1800 from parts of Huntingdon, Lycoming, Mifflin, and Northumberland counties. Cambria County was created on 26 March 1804 from parts of Bedford, Huntingdon, and Somerset Counties. Blair County was created on February 26, 1846 from parts of Huntingdon and Bedford Counties. Finally Fulton County was created on 19 April 1850 from part of Bedford County, setting the county at its current boundaries.

The land was developed into lush farms with woodlands. It was developed as a trading center on the way to Pittsburgh and farther west of Pennsylvania. In 1794 President George Washington came to the county in response to the Whiskey Rebellion.

In the late 19th century, the Bedford Springs Hotel became an important site for wealthy vacationers. It was built near natural springs that had been important to the Native Americans for hundreds of years. During the administration of President James Buchanan, he moved much of his administration to the hotel, which became the informal summer White House.[4] The U.S. Supreme Court met at the hotel once. It was the only time that the high court met outside of the capital{{fact|date=February 2018}}.

During the late 19th century, the county had a population boom, with the number of people doubling between 1870 and 1890. Railroads constructed through the town connected the county with the mining industry. The story of the Lost Children of the Alleghenies originates from Blue Knob State Park in the county.

Geology

{{main|Geology of Bedford County, Pennsylvania}}

Bedford County is situated along the western border of the Ridge and Valley physiographic province, which is characterized by folded and faulted sedimentary rocks of early to middle Paleozoic age. The northwestern border of the county is approximately at the Allegheny Front, a geological boundary between the Ridge and Valley Province and the Allegheny Plateau (characterized by relatively flat-lying sedimentary rocks of late Paleozoic age).[6]

The stratigraphic record of sedimentary rocks within the county spans from the Cambrian Warrior Formation to the Pennsylvanian Conemaugh Group (in the Broad Top area). No igneous or metamorphic rocks of any kind exist within the county.

The primary mountains within the county (From west to east: Wills, Evitts, Dunning, and Tussey mountains) extend from the southern border with Maryland to the northeast into Blair County, and are held up by the Silurian Tuscarora Formation, made of quartz sandstone and conglomerate. Chestnut Ridge is a broad anticline held up by the Devonian Ridgeley Member of the Old Port Formation, also made of sandstone and conglomerate. Broad Top, located north of Breezewood, is a plateau of relatively flat-lying rocks that are stratigraphically higher, and thus younger (Mississippian and Pennsylvanian), than most of the other rocks within the county (Cambrian through Devonian). Broad Top extends into Huntingdon County to the north and Fulton County to the east.

The Raystown Branch of the Juniata River is the main drainage in the northern two-thirds of the county. The river flows to the east through the mountains within the county through several water gaps caused by a group of faults trending east–west through the central part of the county. The river then turns north and flows into Raystown Lake in Huntingdon County. The southern third of the county is drained by several tributaries of the Potomac River. Both the Potomac and Juniata rivers are part of the Chesapeake Bay Watershed.

Several limestone quarries exist in Bedford County, most of which are owned and operated by New Enterprise Stone and Lime Company. Quarry locations include Ashcom, New Paris, Kilcoin, and Sproul.[7]

Two coal fields exist within Bedford County. One is the Broad Top Field in the northeastern corner of the county, and the other is the Georges Creek Field along the southwestern border.[8] Both fields contain bituminous coal. There are abandoned mines in both areas and acid mine drainage is an environmental problem in the Broad Top area, where several fishless streams exist as a result of the discharge from the abandoned mines.[9]

Natural gas fields and storage areas exist in southeastern Bedford County, primarily within folded Devonian rocks south of Breezewood. Another deep gas field exists in the vicinity of Blue Knob on the border with Blair County to the north.[10]
