Myamba Lookout South East Forest National Park Granite tors, Myamba Creek Myamba Creek Spectacular views of granite escarpment can be found at Tuross Falls north east of Nimmitabel in Wadbilliga National Park. The route to this site also takes the visitor through outliers on the Monaro Volcanic Province (described elsewhere on the journey) on the escarpment.

A stop off near Tilba Cemetery A side trip well worth the effort. Heading south, turn left at the turnoff to Central Tilba from the Princes Highway, instead of turning right to the village. Follow the sign to the cemetery towards the coast. The forestry map shows the beach as Wallaga Beach. There is a car park and access to the beach just below the second grave enclosure. The geoheritage treasure is the headland south of the cemetery. The site is best visited at low tide. Approaching the headland, the distinctive features of almost-vertical beds of brownish Ordovician sedimentary rocks stand out. We will meet these very old rocks at other places along the coast. Here, we’ll look at the igneous dykes and quartz veins intruding the Ordovician beds. The first clue is the white slash in the centre of the photo below. The white dykes are chemically similar to the nearby Dromedary intrusion, and were intruded at the same time as the Dromedary mass [Mount Dromedary, now called Gulgaga] An intrusive dyke is a slab-like igneous body whose thickness is smaller than the other two dimensions. Thickness can vary from sub-centimetre scale to many metres, and the lateral dimensions can extend over many kilometres. When intruded, a dyke shoulders aside pre-existing layers or bodies of rock; this means that a dyke is always younger than the rocks that it cuts through.
