The Giant Shawl

About

This calcite crystal formation, called a shawl, has been named the Giant Shawl, and is one of the main features of the River Cave at Jenolan in the Blue Mountains.

Shawls develop over hundreds of thousands of years, whereby rainwater seeping through cracks in the limestone rock follows the surface of the rock shelf and grows outwards, layer upon layer, forming delicate and often wide shawl structures.

The Giant Shawl is quite a few metres in height, and in this beautiful backlighting, the rich colours, affected by iron, can be seen.
