Shoalhaven District Geology

  FIELD GEOLOGY OF THE SHOALHAVEN DISTRICT (PART 10) Chapter 5: Kangaroo Valley  The Cambewarra Range effectively seals in one of Australia’s scenic gems –  Kangaroo Valley . Like any other impressive piece of nature’s handiwork, people have ascribed its origin to anything but the simplest of causes. Since 1818, when white men first entered the “Kangaroo Ground”, as it was then known, there have been numerous suggestions to explain its existence. It has been described as a ‘picturesque sunken valley’, the implication being that its present form is the result of subsidence. Others have thought that it represents a former lake, or that volcanoes led to its formation. The truth is that the Kangaroo River and its tributaries have carried away the products of erosion over a period of many thousands of years, leaving the framework of the rock structure exposed as we see it today.  Volcanic rocks belonging to the upper Berry Formation are mainly confined to the eastern half...

  FIELD GEOLOGY OF THE SHOALHAVEN DISTRICT (PART 9) CHAPTER 4 (CONTINUED) Excursion 4b Nowra – Berry via Cambewarra Lookout  (17 miles) The rocks seen are similar to those seen on the previous excursion. In addition, a number of interesting small igneous intrusions are encountered. Route: Nowra-Cambewarra Range-Bellawongarah-Berry. Proceed to the  Cambewarra Range  via the Moss Vale road. Through  Bomaderry , Permian marine sediments are seen and the road continues over undulating country to the foot of the range. See Excursion 3b.   Stop 1. In the first road cutting after the sign ‘Cambewarra Mountain’, two very weathered dykes may be seen intruding weathered Berry siltstone. Weathered mica is their main characteristic and this identifies them as related to the Good Dog intrusion. At least 14 similar dykes occur along this road and the next ½ mile should be walked to see them properly. Stop 2. Cars can be parked on the left 400 yards past the previous stop...

  FIELD GEOLOGY OF THE SHOALHAVEN DISTRICT (PART 8): THE CAMBEWARRA RANGE AND EXCURSION 4a LIST OF ALL BLOGS AND RELEVANT VIDEOS Chapter 4: The Cambewarra Range Sunrise from Cambewarra Lookout November 1965 Cambewarra Lookout  is renowned for its superb views of the rich dairying country below. The aboriginal word ‘Cambewarra’ is believed to mean ‘smoke coming from mountain’. Many people have therefore assumed that the mountain on which the lookout is situated is an extinct volcano, and its shape seems to support this belief. In fact, this shape is due to a small capping of sandstone, this having preserved the mountain’s flat top. The word probably refers to the fact that mist frequently pours over gaps in the range from  Kangaroo Valley , giving the impression of smoke. Also contrary to common belief, the lookout is actually situated on  Good Dog Mountain ; Cambewarra Mountain is south of the Moss Vale road. When viewed from below, these mountains give an appearance...
