With the appearance of a moon shining down on some alien planet the LED light of one of my fellow cavers illuminates a shelf of rimstone dams.
Low bedding plane cavitites stretch out from the main channel in which we stoop. The decorations get more extravagant deeper into those spaces. I can see an extensive shallow pool surrounded by soda straws. Seeping flowstone blocks an adjacent tunnel. We carefully negotiate our way along the trench; watching for features that are camoflauged on the walls.
