Loysburg Gap
Loysburg Gap is a water gap where Pennsylvania Route 36 and the Yellow Creek pass through Tussey Mountain near Loysburg in Bedford County, Pennsylvania, United States. Yellow Creek flows eastward through the gap towards its junction with the Raystown Branch of the Juniata River. Periglacial boulder fields are present on both sides of the water gap, and the boulders are formed of the Silurian Tuscarora Formation The Silurian Tuscarora Formation — also known as Tuscarora Sandstone or Tuscarora Quartzite — is a mapped bedrock unit in Pennsylvania, Maryland, West Virginia, and Virginia, USA.

Boulder Fields Loysburg Gap PA
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks or stones. The word ''boulder'' derives from ''boulder stone'', from the Middle English ''bulderston'' or Swedish ''bullersten''.

Water Gap
A water gap is a gap that flowing water has carved through a mountain range or mountain ridge and that still carries water today. Such gaps that no longer carry water currents are called wind gaps. Water gaps and wind gaps often offer a practical route for road and rail transport to cross the mountain barrier. Geology A water gap is usually an indication of a river that is older than the current topography. The likely occurrence is that a river established its course when the landform was at a low elevation, or by a rift in a portion of the crust of the earth having a very low stream gradient and a thick layer of unconsolidated sediment. In a hypothetical example, a river would have established its channel without regard for the deeper layers of rock. A later period of uplift would cause increased erosion along the riverbed, exposing the underlying rock layers. As the uplift continued, the river, being large enough, would continue to erode the rising land, cutting thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Route 36
Pennsylvania Route 36 (PA 36) is a long state highway located in the U.S. state of Pennsylvania. The southern terminus is at PA 26 near the Hopewell Township community of Yellow Creek. The northern terminus is at PA 27 and PA 227 in Pleasantville. One of the longest and oldest highways in the commonwealth, PA 36 serves as a major connector between South Central and Northwestern Pennsylvania. In 1955, the highway was designated as the Colonel Drake Highway in honor of Edwin Drake. Route description Bedford and Blair counties PA 36 begins in the Bedford County hamlet of Yellow Creek at PA 26 along the Tussey Mountain range. The distance in Bedford County is brief as the highway enters Blair County and proceeds northward as the Woodbury Pike, intersecting several 800-series state highways like PA 866, PA 868, and PA 869.

Tussey Mountain
Tussey Mountain is a stratigraphic ridge in central Pennsylvania, United States, trending east of the Bald Eagle, Brush, Dunning and Evitts Mountain ridges. Its southern foot just crosses the Mason–Dixon line near Flintstone, Maryland, running north 130 km (80 mi) to the Seven Mountains of central Pennsylvania, near Tusseyville, making it one of the longest named ridges in this section of the Ridge-and-valley Appalachians. The ridge line separates Morrison Cove from the Woodcock Valley and Friends Cove from the Black Valley. Tussey Mountain lies in, and the ridge line forms parts of the borders of, Centre, Blair, Bedford and Huntingdon counties. The Flintstone Creek runs around the southern end of the mountain in Maryland. North of there, small streams run through deep gorges, the Sweet Root and Rainsburg Gaps, near Martin Hill. At Everett the Pennsylvania Turnpike, U.S. Route 30, and the abandoned Huntingdon and Broad Top Mountain Railroad follow the Raystown B ...

Bedford County, Pennsylvania
Bedford County is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 47,577. The county seat is Bedford. 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, Pennsylvania, Allegheny County, on the Allegheny and Monongahela rivers, English colonists built a road between the fort (which was renamed as Fort Pitt (Pennsylvania), 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 Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Periglacial
Periglaciation (adjective: "periglacial", also referring to places at the edges of glacial areas) describes geomorphic processes that result from seasonal thawing of snow in areas of permafrost, the runoff from which refreezes in ice wedges and other structures. "Periglacial" suggests an environment located on the margin of past glaciers. However, freeze and thaw cycles influence landscapes outside areas of past glaciation. Therefore, periglacial environments are anywhere that freezing and thawing modify the landscape in a significant manner. Tundra is a common ecological community in periglacial areas. History Periglaciation became a distinct subject within the study of geology after Walery Łoziński, a Polish geologist, introduced the term in 1909. Łoziński drew upon the early work of Johan Gunnar Andersson. According to Alfred Jahn, his introduction of his work at the 1910 International Geological Congress held in Stockholm caused significant discussion. In the field trip ...

Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized.
