Little Salt Spring, Archaeological site and natural lake in North Port, United States.
Little Salt Spring extends 245 feet deep with a surface pond of 40 feet, featuring numerous vents that feed oxygen-depleted groundwater into the system.
The site contains human bones and artifacts dating back 12,000 years, including a giant land tortoise shell with evidence of human interaction from prehistoric times.
The University of Miami's Rosenstiel School conducts research at this National Register of Historic Places location, examining ancient human activities in Florida.
The spring's anoxic environment below 5 meters creates preservation conditions for Paleo-Indian artifacts and fossil bones of extinct megafauna.
Researchers discovered a deer antler marked with 28 parallel lines, indicating its potential use as a lunar calendar tool approximately 10,000 years ago.
