The article gives me a headache! Has this “spring/sinkhole” always, or nearly always had water in it? The early paleo carbon units left this stuff on a ledge 100’ down a hole in the ground? With or without water in it, that seems a stretch. Is it safe to assume it’s a fresh water spring — or not? Need Tylenol!

The article said it used to be a beach- "In the last ice age, between about 10,000 and 13,000 years ago, the water level was 90 feet lower then than it is today," Gifford said. "It's generally thought that along that early beach area, those early humans left their tools or whatever artifacts they found at that site."
