Uncovering the Past Beneath the Waves
Imagine diving into clear, cool water, not just for the thrill of exploration, but to unlock stories buried for thousands of years. This isn't just an adventure—it's a journey back in time to meet North America's first inhabitants. Their lives, cultures, and survival tactics are hidden not beneath soil, but water. From Florida's freshwater springs to the submerged landscapes of Lake Huron, underwater archaeology is revealing incredible tales of human ingenuity and resilience. Why does this matter to you? It's about more than just curiosity. Understanding our past shapes our present and future. It teaches us about the adaptability of humans, the importance of the environment, and how ancient knowledge can inform current practices. Plus, it's a reminder that history isn't always found in textbooks—it's sometimes submerged, waiting to be discovered by those brave enough to look.

Archaeology
The study of human history and prehistory through the excavation of sites and the analysis of artifacts and other physical remains.

Submerged prehistory
Areas of land that were once above water but have since been submerged, holding archaeological evidence of past human activity.

Megafauna
Large animals, especially those that are now extinct, like mastodons and saber-toothed tigers, which once roamed the earth alongside early humans.

Radiocarbon dating
A method used by scientists to determine the age of an object containing organic material by measuring its carbon-14 content.

Artifact
An object made or used by humans, typically an item of cultural or historical interest.

Sonar (side-scan sonar)
A technique that uses sound waves to create images of the seafloor, allowing archaeologists to find and study submerged sites without having to dive.
