Coles Creek (Pennsylvania)
Coles Creek (also known as Cole's Creek) is a tributary of Fishing Creek, in Columbia County, Pennsylvania and Sullivan County, Pennsylvania, in the United States. It is long and is the first named tributary of Fishing Creek downstream of where East Branch Fishing Creek and West Branch Fishing Creek meet to form Fishing Creek. The creek is on the edge of Columbia County and parts of its watershed are in Luzerne County. The watershed of Coles Creek has an area of 11.6 square miles. There are of streams in the watershed. Most of the watershed is over rock of the Catskill Formation, although a small part of it is over rocks of the Huntley Mountain Formation. The water temperature of the creek ranges from slightly under to slightly under . Coles Creek is named after Ezekiel Cole. Course Coles Creek begins on Central Mountain in southeastern Sullivan County, Pennsylvania and flows south into Sugarloaf Township, Columbia County, near the border between Columbia County, Luzerne Coun ...

Pennsylvania Route 487
Pennsylvania Route 487 (PA 487) is a , north–south state highway running from PA 61 in Shamokin Township, Northumberland County, to PA 87 (near its intersection with US 220) in Dushore, Sullivan County. In Bloomsburg, PA 487 and US 11 share a brief wrong-way concurrency. After its brief concurrency with PA 118, PA 487 goes up a steep grade through Ricketts Glen State Park. PA 487 is used to carry traffic up the Fishing Creek valley. Route description PA 487 begins at an intersection with PA 61 in the community of Paxinos in Shamokin Township, Northumberland County, heading northeast on a two-lane undivided road. The route heads through commercial areas, crossing the Shamokin Valley Railroad before heading across the Shamokin Creek into Ralpho Township, where it becomes West Valley Avenue. The road passes more businesses and continues into a mix of farmland, woodland, and homes. PA 487 reaches the community of Elysburg where it intersects PA 54. After this, the roa ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Mississippian Age
The Mississippian ( , also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas. In North America, where the interval consists primarily of marine limestones, it is treate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huntley Mountain Formation
The Huntley Mountain Formation is a late Devonian and early Mississippian mapped bedrock unit in Pennsylvania, in the United States. Description The formation is composed of relatively soft grayish-red shale and olive-gray sandstone. It is located in north central Pennsylvania. Haystacks The Haystacks are enigmatic mounds of sandstone that outcrop in Loyalsock Creek south of Dushore in Sullivan County. They are a single bed of quartz sandstone with an undulating upper surface with up to one meter relief. The origin of the mounds is debatable. Notable Exposures * The type section of the formation is at Huntley Mountain in Lycoming County, Pennsylvania, on the mountainside just north of the village of Waterville. * Base of the Loyalsock Creek gorge in Worlds End State Park * Haystacks beds, also in Loyalsock Creek Stratigraphy Geologist William E. Edmunds argues that the Huntley Mountain Formation is laterally equivalent to the Rockwell Formation (originally described in ...

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
