Campo de Piedra Pómez

The pumice field of Campo de Piedra Pómez in Catamarca Province covers 280 square kilometres of white and cream volcanic rock at 3,700 metres, sculpted by wind into a maze of corridors, arches, and cave-like chambers that go on for hours in every direction. The wind moves constantly here — not violently but persistently, and it has had 10,000 years to work the pumice into shapes that look carved by a sculptor who had no deadline and infinite patience. There is no tourist infrastructure of any kind on the field itself.

Campo de Piedra Pómez is a blanket of pyroclastic material deposited by the eruption of the Blanco volcanic complex approximately 10,000 years ago, now wind-eroded into a labyrinthine landscape that is unique in South America. The pale pumice rock is porous and lightweight — blocks the size of houses can be shifted by a single person — and the wind erosion has created formations ranging from delicate mushroom columns to enclosed spaces that function as natural shelters. The Río Real passes through the southern edge of the field, producing a surreal contrast of turquoise water against white rock that photographers have been trying to do justice to for twenty years without fully succeeding. Access requires a high-clearance vehicle and a guide — the field's size and uniformity make it genuinely easy to become disoriented.
