The Chilling Tale of Bill McFaden in the Depths of Little Dismal Sink

Little Dismal Sink, Leon County, Florida	Bill McFaden

In May 1988, during an exploration of the Little Dismal Sink cave in Florida, a seemingly routine dive turned into a harrowing ordeal. But before we dive into the depths of the incident, let’s equip ourselves with some crucial knowledge.

Gearing Up: The Diver’s Essentials

Imagine a diver’s toolkit: a diving mask for crystal-clear vision, a trusty computer monitoring depth and decompression, and tanks filled with life-giving air. Not to forget the diving suit, our underwater armor. But not just any suit – a dry suit, a technological marvel that keeps divers warm and dry even in the inky blackness of deep caves.

Mission: Mapping the Deep

The goal of this particular dive was ambitious: to map the uncharted territory of the cave’s “deep section.” This meant squeezing through tight passages like the aptly named “Peanut Room” and navigating a near-vertical shaft leading to the mysterious sixth room.

Understanding the Dry Suit: A Matter of Life and Breath

But before we join the divers on their descent, let’s unravel the secrets of the dry suit. This ingenious gear traps a layer of air around the diver, providing warmth and insulation. However, as they go deeper, the water pressure shrinks the suit, demanding divers to add air from their tanks to maintain comfort and avoid getting squeezed. Crucially, managing this air becomes paramount during ascent, as uncontrolled expansion can lead to a dangerous condition known as “suit squeeze.”

Now, armed with this essential knowledge, we’re ready to plunge into the depths and explore the unfolding events in the Little Dismal Sink…

The Dive Begins

May 15th, 1988: a seasoned team of divers, including veterans like Parker Turner, Bill Gavin, and Bill Main, stood poised on the brink of the Little Dismal Sink. With a practiced glance, they adjusted equipment and signaled descent, ready to unravel the secrets hidden within the earth’s embrace.

Descending into Depths:

The plan unfolded smoothly. Divers dispersed, some meticulously collecting rock samples in the first cavern, while others, like the intrepid Bill Gavin, plunged into the abyss of the deep section.

A Lone Wolf in the Downstream:

Gavin, seasoned in the art of deep-sea and cave explorations, ventured solo into the downstream tunnel. Here, darkness reigned supreme, broken only by the flicker of his dive light illuminating the unknown passage.

Upstream Turbulence:

Meanwhile, Bill Main and Bill McFaden navigated the challenging upstream tunnel. Low ceilings and treacherous silty floors conspired to hinder their progress. McFaden’s equipment tangled with the lifeline, creating an unexpected hurdle. Yet, their expertise and unwavering determination shone through, allowing them to meticulously map a significant portion of the treacherous passage.

Navigating Darkness: A Close Call in the Depths

Low on gas, Main’s signal echoed through the silent cave – it was time to head back. Though slow, the dive had been fruitful. Following the lifeline back, Main and McFaden meticulously retraced their steps, aiming for a safe exit.

But the silty tunnel held challenges. Visibility plunged with the slightest movement, forcing Main to halt and confirm McFaden’s position repeatedly. The lifeline, their guiding star, was crucial in these murky stretches.

A Tense Pause: Where’s McFaden?

Reaching the sixth chamber, Main waited. McFaden was missing. Alarm bells clanged. Seeking help, Main turned to Bill Gavin, who’d finished surveying a different tunnel.

Upstream Scramble: A Race Against Time

Understanding the urgency, Gavin plunged back into the upstream tunnel. Blindfolded by swirling silt, he navigated by touch, a desperate search for McFaden. Success! He found him, straying from the lifeline. Together, they retraced their steps, precious minutes ticking by.

Precarious Air Situation

The air was thin, the pressure immense. With only 1,000 PSI left, Gavin held the lifeline for their team – enough air for one to reach the decompression tanks. McFaden, sharing Gavin’s breath, became a ticking clock.

DPV: A Glimmer of Hope

In the fifth room’s well, a beacon emerged – the Dive Propulsion Vehicle (DPV). This underwater chariot offered a shot at escape. McFaden, his own air gone, clung to Gavin’s lifeline.

Ascending Chaos

Their ascent with the DPV was fraught with peril. Buoyancy became a frantic dance. Panicked by the rising pressure, McFaden lost control of his dry suit. Efforts to regain control were futile, leading to a terrifying rush through the fifth room’s ceiling.

Desperate Scramble

With buoyancy gone awry and air dwindling fast, the team fought their way towards the decompression tanks. McFaden’s ballooning suit, Gavin’s fading air, and the looming decompression limits – each a threat to their fragile survival.

Critical Decision Point

Main stared at McFaden, inflating uncontrollably, desperation churning in his gut. To save him, he could cut the suit, a risky gamble with unknown consequences. But the clock ticked. Biting his lip, Main chose to control McFaden’s ascent, a perilous path, but one with a clearer course.

Darkness Descends

Their valiant fight ended in heartbreak. Gavin’s air sputtered, and McFaden, unconscious and lost, paid the ultimate price for the rapid ascent. Main, alone but resolute, hauled Gavin through the restrictions, reaching the life-giving chambers just as his own air neared its end.

Unraveling the Tragedy

The post-mortem brought a grim truth: McFaden succumbed to intra-alveolar barotrauma (IAB), gas bubbles forming in his body during the frantic ascent. This tragedy, etched in their memories, became a catalyst for change. New equipment, stricter protocols – all implemented to prevent another diver from meeting the same fate.
