Cave Gallery (IMAGE)
Caption
Dimitri Laurent explores a typical gallery in the Nébélé Cave, that was formed by sulfuric acid speleogenesis. You can see a deep notch that indicates the former presence of a river, and sodium sulfate on the left that is produced from weathering by sulfuric acid (credit: Christophe Durlet).
