Lock Haven is 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 2010 census, Lock Haven's population was 9,772. 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 National Register of Historic Places—Memorial Park Site, a significant pre-Columbian archaeological find; Heisey House, a Victorian-era museum; and Water Street District, an area with a mix of 19th- and 20th-century architecture. A levee, completed in 1995, protects the city from further flooding. While industry remains important to the city, about a third of Lock Haven's workforce is employed in education, health care, or social services.

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 plants near the site and its distance from well-documented wild populations is evidence that the gourds were intentionally brought to the location by humans.Memorial Park contains the only area on the West Branch side of the point of land between the river and the creek that has not been disturbed by subsequent development. Alluvial deposits 20 to 28 inches (51 to 71 cm) deep cover the site and have protected it from recent activity on the surface. The Veterans of Foreign Wars acquired the property in the 1920s and used it for a park.Piper Aircraft bought the fields adjacent to the park in the 1960s to use for airport runways and airplane storage. In the 1970s, Conran A. Hay, a consultant, discovered the prehistoric site during an archeological survey conducted for the United States Army Corps of Engineers. Subsequent research sponsored by the Office of State Archeology and the Office of Historic Preservation of the Pennsylvania Historical and Museum Commission in 1980 helped determine the site boundaries.
