Coffee and Cream from the Nullarbor Plain

A number of caves on the Nullarbor Plain contain deposits that are known as "Coffee and Cream". These deposits consist of a very dark brown powder adjacent/mixed with a very white powder to create the "Coffee and Cream". The origin of the powders has been determined to result from roof fretting.

Here are a few photographs of some "Coffee and Cream".
