This area is used to be thought of a result of advancing sand engulfing an ancient forest of coastal trees that once covered the sea cliff. Actually the formation is a collection of hollow tubes of limestone called "solution pipes" eroded by million years of rainfall. Most pipes around Bridgewater cape are around 3 metres high. Some can be 20 metres though.
