These magical and extremely intriguing Boulders are known as cannon ball concretions made from mudstone. Some are particularly large.
It is believed that millions of years ago rivers carried sediment from eroding land out to sea. Shells and trees were also carried out to sea and were trapped in the sediment. The sea water contained dissolved chemicals and formed a cement around what was left of the buried shells and plant material. The cement in this case is calcium carbonate. The organic material seems to create a node for this process to occur.
They have to be seen to be believed. A great walk over farm land with views for miles and then into this bush setting is just magical.
The walk back up the hill can be challenging to some, a reasonable degree of fitness is required.
Please respect our farm. Respect and stay away where possible from all stock and supervise children at all times near water.
PLEASE NOTE - BOULDERS WILL BE CLOSED FROM AUGUST TO END OF SEPTEMBER DUE TO LAMBING TIME. THANK YOU.
