The Memorial Park Site 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 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.
