panicked few seconds, I raced away from the murk, staying just ahead in clear water, as if I might suffocate if the silt engulfed me. The reaction was not befitting a marine biologist who has logged hundreds of dive hours.
Me, the so-called expert diver—but that’s exactly what I did. It’s the way our brains work. When darkness triggers the flight mechanism, we bolt for light because light means safety. It means freedom . . . and air.
Air, suddenly, was something that was in limited supply.
We had been exploring the lake’s shallow perimeter for thirty-seven minutes . Because I’m obsessive when it comes to safety, and because I was the most experienced diver, I’d insisted that we not go deeper than thirty-three feet, which is the minimally more dangerous demarcation between two and three atmospheres.
The lake was a geological oddity—a teardrop-shaped pool, central Florida, northwest of a crossroad village named Venus, three miles from the nearest dirt road. We’d had to bushwhack across plains of palmetto scrub and pasture, cutting a track for Arlis Futch’s big-tired truck. It had taken all morning and part of the afternoon.
The lake sat between two ridges, a natural basin with cypress trees on the southern perimeter, then a pocket of cattails to the north where the lake narrowed. Beyond lay a marshy expanse of saw grass and cypress trees, a variety of Florida swamp where reptiles of every variety thrive, and so most people avoid such areas for a reason.
The lake consisted of an acre of water, which is about the size of a football field. It was manageable, I thought.
The water was clear and shallow in all but one dark area. There, the bottom funneled downward, vanishing into depths that were linked to the surface by pillars of silver light.
A “bottomless lake” is the colloquial term but inaccurate. A “cenote” is what similar sinkholes are called in Central America. A thousand years ago, Mayan priests dropped gold offerings into their depths—they gifted the heads of their enemies. Such places were considered holy. Ojos de Dios. The Eyes of God.
This lake was, in fact, the uppermost promontory of a water column that connected with the Floridan Aquifer. “Underground river”—another colloquial term. It was the safest of places to swim and dive, if you didn’t stray too deep . . . and if there weren’t man-sized gators in residence.
There were no gators. We’d made sure of that.
Alligators are, of course, a concern when diving the lakes and rivers of Florida. Because Arlis, a state-licensed hunter, had heard rumors that an oversized gator sometimes inhabited the lake, we took special precautions. I had done the research to confirm what I remembered and what Arlis swore was true: Alligators have a bottom time of two hours, max, usually much less. So we had watched, and waited, circling the lake several times. The precaution put us in the water later than we expected, with only an hour of good light left.
So what? It was the prudent thing to do.
I went in the water first. I did a lap across the lake and back, wearing a mask so I could have a look at the bottom. Tomlinson joined me on a quick bounce dive. Then we checked out Will’s scuba skills before continuing. It was only the boy’s second open-water dive, but he demonstrated more confidence than most hobbyists and more poise than at least a few so-called pros.
Even so, all the beginner protocols were in effect, plus the standard protocols employed when diving a remote inland area. We had brought the requisite emergency gear, in case we had bad luck, along with some basic salvage equipment—in case we had very good luck.
There was a reason we had brought salvage gear.
All divers enter the water in hope of finding something, anything, unexpected. Our hopes were more specific. We knew exactly what we were after—just as we knew how unlikely it was that we would find what we hoped to find.
We each carried a waterproof flashlight,
