During July 2019, an international team of SPLASH archaeologists mapped a precontact quarry in the Gulf of Mexico that was likely submerged 5,000 years ago.

SPLASH archaeologists have extensive excavation experience of submerged precontact archaeological sites. Our research is oriented around theoretical and methodological techniques which promotes a more holistic study of past cultures.
