Photographer's Note

This shot is from the lucas caves. The formation on the left is called a shawl. Water reaching the roof of a cave does not always form drops, sometimes it trickles down a rockface depositing a narrow strip of calcite that results eventually in a thin sheet growing at an angle from the wall. Shawls often contain interesting folds which occur because the initial trickle turned from side to side in its downward path along the rockface. The rich coloured banding that is often seen, is caused by other minerals, such as iron oxide, present in the solution.
