The Architecture Caves Made Alone is a 3D virtual gallery on MyGallery3D, a walkable online exhibition of 15 works. Step inside and explore it in your browser: no app, no headset.
Walk through this 3D virtual museum of caves in your browser. Every chamber here was carved without a hand: the architecture is what the rock lost.
Rain picks up carbon dioxide on the way down, turns into weak carbonic acid, and spends millions of years eating limestone. Cracks widen into passages; passages widen into rooms. Mammoth Cave in Kentucky has 675.9 km of surveyed passage. The single largest passage known, in Son Doong Cave in Vietnam, runs 4.6 km and stands over 140 m high and wide along part of its length.
Not every cave was made by rain. Beneath Carlsbad Caverns lie petroleum reserves, and hydrogen sulfide seeping up from them met oxygen in the groundwater and became sulfuric acid. That acid dissolved the limestone upward, hollowing the rock from underneath. The gypsum left inside the cave is the byproduct, and the proof. The Big Room it opened is the largest chamber in North America.
Nearly 350 caves in France and Spain hold prehistoric art. The subjects are almost all large animals: bison, horses, aurochs, deer, and stencilled hands. Plants make up less than 1% of the symbols in European cave art. The painters at Lascaux left mostly reindeer bones behind, yet reindeer never appear on the walls. They were not painting their dinner.
A stalagmite grows one drip at a time, and the drips remember. Close rings mean little rainfall, wider spacing means heavier rain. Uranium-thorium and radiocarbon dating fix the layers in time, and oxygen and carbon isotopes inside them track temperature, rainfall and vegetation across roughly the past 500,000 years. Speleothems at Richards Spur in Oklahoma carry climate data from 289 million years ago.
