Amazing what wonders can lead from an unassuming hole in the ground: crystal spires, cathedrals of calcite, gypsum cascades. To access this magical cave, however, a certain suffering must be endured and one must overcome more than a little fear. For the cavers of Into Darkness, this means squeezing through impossibly constricted spaces, exhaling everything in their lungs to make their bodies improbably flat, feeling their heartbeats thud into intractable rock, or holding themselves up by nothing more than their armpits. The contortion and pain is worth it, though, as they emerge into a dazzling underworld chamber of secrets and experience one of our world’s few final frontiers.
