Bald Eagle Creek (West Branch Susquehanna River tributary)

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.

The Jay Street Bridge crosses the West Branch Susquehanna River between Lock Haven on the south bank and Lockport on the north. The original structure, completed for the Lock Haven Bridge Company by the E. Kirkbride Company in 1852, was a covered bridge about 800 feet (240 m) long. A two-story toll house, 48 feet (15 m) long and 18 feet (5.5 m) wide was later added at the foot of the bridge on the Lock Haven side. Travelers using the bridge passed through an archway in the center of the toll house. The bridge included a covered pedestrian walkway on the downstream side.After the wooden bridge was destroyed by fire in 1919, it was replaced by an iron bridge, and a steel girder bridge replaced the iron bridge in 1986. State Route 664, the southern terminus of which is in Lock Haven, crosses the river over the steel bridge. The bridge is slightly upstream of Lock Haven's Canal Park, featuring remnants of the Bald Eagle Crosscut Canal. It is also slightly upstream of the Lock Haven Dam (also known as the Dunnstown Dam), built in the 19th century to provide water to the West Branch Canal, which ran parallel to the Lockport and Dunnstown side of the river. Canal boats crossed the pool behind the dam by means of a cable ferry between Lock No. 34, about 2,000 feet (610 m) east of the bridge on the Lockport side, and Lock No. 35 on the Lock Haven side.The steel bridge is 8.5 metres (28 ft) wide and about 250.5 metres (822 ft) long. It has an operating rating (maximum allowable weight of a vehicle using the bridge) of 60.8 metric tons (67.0 short tons). In 2007, the average daily traffic count for the bridge was 3,646 vehicles.
