Lock Haven, Pennsylvania
Lock Haven is a city in, and the county seat of, Clinton County, in the U.S. state of Pennsylvania. Located near the confluence of the West Branch Susquehanna River and Bald Eagle Creek, it is the principal city of the Lock Haven Micropolitan Statistical Area, itself part of the Williamsport–Lock Haven combined statistical area. At the 2020 census, Lock Haven's population was 8,108. Built on a site long favored by pre-Columbian peoples, Lock Haven began in 1833 as a timber town and a haven for loggers, boatmen, and other travelers on the river or the West Branch Canal. Resource extraction and efficient transportation financed much of the city's growth through the end of the 19th century. In the 20th century, a light-aircraft factory, a college, and a paper mill, along with many smaller enterprises, drove the economy. Frequent floods, especially in 1972, damaged local industry and led to a high rate of unemployment in the 1980s. The city has three sites on the ...

Paleo-Indians
Paleo-Indians were the first peoples who entered and subsequently inhabited the Americas towards the end of the Late Pleistocene period. The prefix ''paleo-'' comes from . The term ''Paleo-Indians'' applies specifically to the lithic period in the Western Hemisphere and is distinct from the term ''Paleolithic''.''Paleolithic'' specifically refers to the period between million years ago and the end of the Pleistocene in the Eastern Hemisphere. It is not used in New World archaeology. Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge ( Beringia). This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). Small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska. From BCE ( BP), ice-free corridors developed along the Pacific coast and valleys of North America. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Common Era
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year. The expression can be traced back to 1615, when it first appears in a book by Johannes Kepler as the (), and to 1635 in English as " Vulgar Era". The term "Common Era" can be found in English as early as 1708, and became more widely used in the mid-19th century by Jewish religious scholars. Since the late 20th century, BCE and CE have become popular in academic and scientific publications on the grounds that BCE and CE are religiously neutral terms. They have been promoted as more sensitive to non-Christia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levee
A levee ( or ), dike (American English), dyke (British English; see American and British English spelling differences#Miscellaneous spelling differences, spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the river banks, banks of a river, often intended to flood control, protect against flooding of the area adjoining the river. It is usually soil, earthen and often runs parallel (geometry), parallel to the course of a river in its floodplain or along low-lying coastlines. Naturally occurring levees form on river floodplains following flooding. Sediment and alluvium are deposition (geology), deposited on the banks and settle, forming a ridge that increases the river channel's capacity. Alternatively, levees can be artificially constructed from fill dirt, fill, designed to regulate water levels. In some circumstances, artificial levees can be environmental degradation, environmentally damaging. Ancient civilization ...

Memorial Park Site
The Memorial Park Site (designated 36CN164) is an archaeological site located near the confluence of Bald Eagle Creek and the West Branch Susquehanna River in Lock Haven in the U.S. state of Pennsylvania. Research projects conducted at the site since 1979 have found prehistoric cultural deposits that collectively span 8,000 years. Stratified in age-related sequence, the deposits represent every major prehistoric period from the Middle Archaic to the Late Woodland. The site's dominant component holds the remains of an early Late Woodland (500–1000 CE) village inhabited by people of the Clemson Island culture. The convergent streams and their two valleys made the site readily accessible to pre-Columbian people living in both drainage basins. Among the components of the site are two strata, dating from 5000-6000 and c. 2600 BP respectively. Both components were radiocarbon dated from fragments of ''Cucurbita pepo'', the squash plant; the absence of wild squash ...
