Swatara Creek
Swatara Creek (nicknamed the Swatty) is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 8, 2011 tributary of the Susquehanna River in east-central Pennsylvania in the United States. It rises in the Appalachian Mountains in central Schuylkill County and passes through northwest Lebanon County before draining into the Susquehanna at Middletown in Dauphin County. The name "Swatara" is said to derive from a Susquehannock word, ''Swahadowry'' or ''Schaha-dawa'', which means "where we feed on eels". Geography Swatara Creek rises in the Appalachian Mountains in central Schuylkill County, on Broad Mountain north of the Sharp Mountain ridge, approximately west of Minersville. It flows southwest in a winding course, passing south of Tremont, then cutting south through the ridges of Sharp Mountain and Second Mountain. It passes through Swatara State Park then turns south to pass through Swatara Gap in the Blue M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterville Bridge
The Waterville Bridge is a lenticular truss bridge designed and manufactured by the Berlin Iron Bridge Co. It was built in 1890. It was relocated from Waterville, Lycoming County, Pennsylvania, to Swatara State Park in Lebanon County, Pennsylvania, in 1985. It was listed on the National Register of Historic Places in 1988.

Blue Mountain (Pennsylvania)
Blue Mountain, Blue Mountain Ridge, or the Blue Mountains of Pennsylvania, is a ridge of the Appalachian Mountains in eastern Pennsylvania. Forming the southern and eastern edge of the Ridge-and-Valley Appalachians physiographic province in Pennsylvania, Blue Mountain extends from the Delaware Water Gap on the New Jersey border in the east to Big Gap in Franklin County in south-central Pennsylvania at its southwestern end. Views of Blue Mountain dominate the southern tier of most eastern and central Pennsylvanian counties, providing an ever-visible backdrop cutting across the northern or western horizon. Most transport corridors and road beds piercing the barrier necessarily pass through either large water gaps (west to east: the Susquehanna, Schuylkill, Lehigh and Delaware River valleys) or wind gaps, low gaps in the ridge caused by ancient watercourses. The barrier ridge forms a distinct boundary between a number of Pennsylvania's geographical and cultural regions. To the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lebanon County, Pennsylvania
Lebanon County ( Pennsylvania Dutch: Lebanon Kaundi) is a county in the Commonwealth of Pennsylvania. As of the 2010 census, the population was 133,568. Its county seat is the city of Lebanon. The county was formed from portions of Dauphin and Lancaster counties in 1813, with minor boundary revisions in 1814 and 1821. Lebanon County comprises the Lebanon, Pennsylvania, metropolitan statistical, which is part of the Harrisburg–York–Lebanon combined statistical area. Lebanon is 72 miles northwest of Philadelphia, which is the nearest major city. Geography According to the U.S. Census Bureau, the county has a total area of , of which is land and (0.2%) is water. Most of it is drained by the Swatara Creek into the Susquehanna River while some eastern portions are drained by the Tulpehocken Creek (which originates in the county near Myerstown) eastward into the Schuylkill River. It consists in large part of a valley. Climate The county has a hot-summer humid contine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Route 72
Pennsylvania Route 72 (PA 72) is a north–south state route located in southeast Pennsylvania. The southern terminus of the route is at U.S. Route 222 (US 222) and PA 272 in Lancaster. The northern terminus is at PA 443 north of Lickdale in Union Township. PA 72 serves as a major road connecting Lancaster and Lebanon counties, serving East Petersburg, Manheim, Cornwall, Lebanon, and Jonestown. The route intersects several major roads including US 30 and PA 283 north of Lancaster, the Pennsylvania Turnpike ( Interstate 76, I-76) south of Cornwall, US 322 along a concurrency on a freeway bypassing Cornwall, US 422 in Lebanon, US 22 near Jonestown, and I-81 via Fisher Avenue in Lickdale. The portion of the road between Lancaster and Lebanon was chartered as two separate private turnpikes in the 1850s. PA 72 was designated in 1927 to run concurrent with US 230 between the Maryland state line and Lancaster, with US 222 replacing US 230 a year later. In 1928, PA 72 was exte ...

Interstate 81
Interstate 81 (I-81) is a north–south (physically northeast–southwest) Interstate Highway in the eastern part of the United States. Its southern terminus is at I-40 in Dandridge, Tennessee; its northern terminus is on Wellesley Island, New York at the Canadian border, where the Thousand Islands Bridge connects it to Highway 137 and ultimately to Highway 401, the main Ontario freeway connecting Detroit via Toronto to Montreal. The major metropolitan areas along the route of I-81 include the Tri-Cities of Tennessee; Roanoke in Virginia; Harrisburg and the Wyoming Valley in Pennsylvania; and Syracuse in New York. I-81 largely traces the paths created down the length of the Appalachian Mountains through the Great Appalachian Valley by migrating animals, indigenous peoples, and early settlers. It also follows a major corridor for troop movements during the Civil War. These trails and roadways gradually evolved into US Route 11 (US 11); I-81 parall ...

Appalachian Trail
The Appalachian Trail (also called the A.T.), is a hiking trail in the Eastern United States, extending almost between Springer Mountain in Georgia and Mount Katahdin in Maine, and passing through 14 states.Gailey, Chris (2006)"Appalachian Trail FAQs" Outdoors.org (accessed September 14, 2006) The Appalachian Trail Conservancy claims the Appalachian Trail to be the longest hiking-only trail in the world. More than three million people hike segments of the trail each year. The trail was first proposed in 1921 and completed in 1937 after more than a decade of work. Improvements and changes have continued since then. It became the Appalachian National Scenic Trail under the National Trails System Act of 1968. The trail is maintained by 31 trail clubs and multiple partnerships, and managed by the National Park Service, United States Forest Service, and the nonprofit Appalachian Trail Conservancy. Most of the trail is in forest or wild lands, although some portions traverse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swatara State Park
Swatara State Park is a Pennsylvania state park in Bethel, Swatara and Union Townships, Lebanon and Pine Grove Township, Schuylkill Counties in Pennsylvania in the United States. of Swatara Creek lie within the park's boundaries, which are roughly formed by Pennsylvania Route 443 to the north and Interstate 81 to the south. The park is in a valley in the ridge and valley region of Pennsylvania between Second Mountain (north) and Blue Mountain (south). Swatara State Park is a fairly new park for the Commonwealth of Pennsylvania. It was opened in 1987 and is still largely undeveloped. The Pennsylvania Department of Conservation and Natural Resources is working on plans to further develop the lands of Swatara State Park. The original plans called for the building of a dam and reservoir for recreational fishing and boating as well as to provide drinking water for the City of Lebanon. The PADCNR explored plans for developing the park without the recreational lake/reservoir, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the abs ...

Geology Of Pennsylvania
The Geology of Pennsylvania consists of six distinct physiographic provinces, three of which are subdivided into different sections. Each province has its own economic advantages and geologic hazards and plays an important role in shaping everyday life in the state. They are: (listed from the southeast corner to the northwest corner) the Atlantic Coastal Plain Province, the Piedmont Province, the New England Province, the Ridge and Valley Province, the Appalachian Plateau Province, and the Central Lowlands Province. A majority of the rocks in Pennsylvania exposed at the surface are sedimentary and were deposited during the Paleozoic Era. Almost all of the metamorphic and igneous rocks are confined to the southeast portion of the state. A total of four orogenies have affected the rocks of the Commonwealth including the Grenville orogeny, the Taconic orogeny, the Acadian orogeny, and the Appalachian orogeny. The Appalachian event has left the most evidence and has continued to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
