Two accelerator mass spectrometry (AMS) dates, 5404 \textpm 552 B.P. (AA-19129) and 2625 \textpm 45 B.P. (AA-19128), confirm the presence of mid-Holocene and early late Holocene cucurbit (Cucurbita pepo), respectively, at the Memorial Park site (36CN164) in north-central Pennsylvania. This is the second documented occurrence of mid-Holocene cucurbit and the first documented occurrence of domesticated early late Holocene cucurbit in the northern Eastern Woodlands east of the Allegheny Front. These occurrences help to establish the use of cucurbits in the Northeast on a timescale equivalent to that in the riverine interior, with the exception of the very earliest riverine interior dates. The Northeast has contributed little toward our understanding of prehistoric agricultural evolution in the Eastern Woodlands. The Memorial Park cucurbits and the mid-Holocene cucurbit recently reported at the Sharrow site in Maine indicate that greater efforts are needed to document pre-maize agricultural behavior in this area to increase our knowledge of the full range of pre-maize agricultural behavior in the Eastern Woodlands.
