The Pac Man archaeological site (23SL370) was a combined field school and rescue archaeological site excavated by St. Louis Community College - Florissant Valley during the summer of 1983. The site was visited in the 1970s by David Evans of the University of Missouri - Columbia. A low mound was being bulldozed from the crest of the hill and he examined the mound to determine if it warranted excavation. He also visited other sites in the general area. Sadly, no work was carried out before the mound was removed.

Joe Harl, an archaeologist working with the University of Missouri - St. Louis during the 1980s, revisited the hilltop and lower terrace. He supervised several seasons of excavation on the Spanish Village Site (23SL69) which was situated on a terrace below the Pac Man hilltop.

Several trashpit features were discovered by the SLCC crew excavating on the hilltop. Fieldwork at the site was supervised by Professor Michael Fuller. Two radiocarbon samples were dated. One sample dated 170 +/- 320 BC belongs to the Middle Woodland Period. the second radiocarbon date is AD 670 +/- 90 and belongs to the Late Woodland Period. The Late Woodland C-14 date came from a trash pit containing cordmarked pottery sherds, a chert microlith tool, small burnt pieces of mammal bone, burnt limestone, fragments of a burnt basket, and carbonized seeds. Dr. Leonard Blake identified the carbonized seeds as Maygrass (Phalaris caroliniana), goosefoot (Chenopodium sp.) and hickory nut (Carya sp.).

The Middle Woodland Period C-14 date came from a trashpit that contained a few pottery sherds, small pieces of daub (dried or fired clay from a wall packing), and pieces of carbonized hickory shell (Carya sp.).
