There’s a jungle inside Vietnam’s mammoth cavern. A skyscraper could fit too. And the end is out of sight.
I recognize Jonathan Sims’s clipped, British military accent but have no idea what he’s talking about. My headlamp finds him, gray muttonchops curling out from beneath his battered helmet, sitting alone in the blackness along the wall of the cave.
“Carry on mate,” growls Sims. “Just resting a buggered ankle.”
The two of us have roped across the thundering, subterranean Rao Thuong River and climbed up through 20-foot blades of limestone to a bank of sand. I continue alone, following the beam of my headlamp along year-old footprints.
