When Sergio García-Dils de la Vega kissed his girlfriend, Pilar Orche, goodbye at the entrance to Krubera Cave, he promised to return the next day. But after teammate Bernard Tourte bruised his side in a tight passage, García-Dils decided to stay with him at an underground camp, missing his chance to return to the surface before going deeper. It was two weeks before Pilar Orche saw her boyfriend again.
Our expedition, however, had come prepared for a long siege, bringing more than five tons of gear to the cave. Ever since 1956, when explorers in France first descended below 1,000 meters (3,281 feet), generations of cavers had dreamed of achieving the 2,000-meter (6,600-foot) mark. Would Krubera take us there?
Cutting a jagged path through the limestone of the Arabika massif on the edge of the Black Sea, the "trail" into Krubera Cave drops down a chain of pitches, cascades, and pits—some more than 100 meters (300 feet) deep—connected by narrow rift passages called meanders. The cave, located in the separatist region of Abkhazia, was named after Russian geologist Alexander Kruber. In 1960 researchers from the Republic of Georgia explored it to a depth of 90 meters (295 feet). Two decades later, I organized a series of expeditions to investigate new deep caves, using dye traces in cave streams to probe Arabika's potential depth. In 2001 a team led by Ukrainian Yuri Kasjan set a world record in the cave of 1,710 meters (5,610 feet). Last July a Moscow-based team extended that to 1,775 meters (5,823 feet). Our hope was to find a path past 2,000 meters (6,600 feet).
* * * * * *Like mountaineers scaling a Himalaya peak, our expedition of 56 cavers from seven countries established a series of campsites, at depths of 700, 1,215, 1,410, and 1,640 meters (2,300, 3,986, 4,630, and 5,380 feet). There team members cooked meals, slept five and six to a tent, huddled for warmth, and worked for up to 20 hours at a stretch.
By the third week our downward progress was blocked by a sump at a depth of 1,775 meters (5,823 feet). Gennadiy Samokhin surfaced after a dive to examine a tight squeeze at the bottom of the ten-meter-deep pool. "No chance to get through," he said.
Searching for a route around the sump, Sergio García-Dils de la Vega braved a cascade of near-freezing water. Also unsuccessful, he discovered to his dismay that his waterproof dry suit had holes in it. "The water was so cold I lost the feeling in my fingers," he said later. In a last-ditch effort, Denis Kurta and Dmitry Fedotov squeezed through a narrow, 100-meter-long (300-foot-long) passage called the Way to the Dream, which successfully bypassed the sump and pointed steeply down. It was the breakthrough we'd hoped for.
