The same calcium carbonate, packed into a different crystal lattice, grows outward in needles and curling petals that pay no attention to which way is down — clusters that look less like rock than like something that bloomed. In a pale chamber under the sertão of Bahia, the Gruta da Torrinha holds one of these that is reckoned the second largest in the world.

Gruta da Torrinha: The White Chamber

The great aragonite flower sits in the Salão Branco — the White Chamber — on the third of the cave's three visitor routes, which is to say you have to want to see it. Aragonite forms under fussier conditions than ordinary calcite: it wants particular water chemistry, particular h...

Gruta da Torrinha: Needles of Glass, Water With No Sky

Photo credit João Carlos Figueiredo, CC BY-SA 3.0. The aragonite is the headline, but Torrinha's reputation among cavers rests on the sheer range of what is packed into it. There are helictites — the contortionist relatives of the stalactite, twisting sideways and upward as if the rules had been suspended. There are needles of gy...

Gruta da Torrinha: 1850, 1992, and Fourteen Kilometres

Photo credit Dimitry B. from London, CC BY 2.0. The cave was found in 1850, but for well over a century nobody measured it properly. The first serious survey came in 1992, when a French caving group mapped an initial 600 metres of passage. The figure now stands at some 14,000 metres mapped — fourteen kilometres of surveyed voi...

The cave lies beneath the village of Torrinha, about 15 kilometres from the town of Iraquara and a kilometre off the highway, inside the Marimbus/Iraquara Environmental Protection Area on the northern flank of the Chapada Diamantina. Iraquara is cave country in the fullest sense ...

Gruta da Torrinha: The Plateau Above

The Chapada Diamantina takes its name from the diamonds that drew prospectors into these highlands in the nineteenth century and emptied out again when the strikes failed; the Parque Nacional da Chapada Diamantina,...
