In 2000, a brutal drought baked north-central Florida. Newnan's Lake shrank to a muddy soup. Then, the lakebed exposed secrets that had been buried for thousands of years. Locals spotted wooden planks sticking out of the muck, which turned out to be ancient watercraft. Archaeologists eventually documented 101 dugout canoes. Let that number sink in. It is the largest concentration of prehistoric vessels on Earth. Most were carved from longleaf pine. The oxygen-starved mud kept them perfectly preserved.
Radiocarbon testing blew scientists away. Some wood dated back 5,000 years. That means hunters paddled these waters during the Middle Archaic period, roughly when Egyptians built the first pyramids. But why did so many end up in one spot Native people probably weighted the canoes with stones to sink them intentionally, protecting the pine from dry rot. Over three millennia, Lake Pithlachocco served as a busy regional transit hub. It was essentially a massive underwater parking lot.
