West MacDonnell Ranges – The Red Centre

It took some time but The Doc has finished his Guide on the West MacDonnell Ranges. The Guide starts and finishes at Alice Springs in the Northern Territory. The Guide is here.

You can then do the East MacDonnell Ranges, that Guide is here.

The Guide on the West MacDonnell Ranges has detailed maps, location notes and images. The number of images meant The Doc had to use high compression and so there are some artefacts in some images. It is a very detailed Guide. You could easily spend 2 or 3 weeks doing the West MacDonnell Ranges and another week doing the East MacDonnell Ranges.

Textures of the Australian Bush: Northern Territory

New report of the textures of the Northern Territory has been posted, here.

Putty Beach, Bouddi National Park, Central Coast of NSW

The Doc has wanted to visit and photograph the sandstone here for some time, with no success (one or two failed attempts). So he booked 2 nights at Copcabana this week to visit and take photographs.

Here, the sandstone made up of tessellated pavement and Liesegang rings. They do not fully understand how these rings occur, but they do occur in sedimentary rock with a cross cut pattern. Iron and other minerals must be present creating the patterns. The is a heavy iron layer in this rock, you can see iron oxide or rust layers when the iron is exposed to water and oxygen.

Technically “there is a precipitation process that is thought to be the catalyst for Liesegang ring formation referred to as the Ostwald-Liesegang supersaturation-nucleation-depletion cycle.” OK?

A small selection of the spectacular sandstone.

Putty Beach also has a nice rock platform with some large waves. This place must be spectacle in heavy surf, as it was great with minimal waves. Enjoy.

Newhaven Sanctuary, Central Australia

On the trip home from the Kimberley The Doc visited AWC’s Newhaven Sanctuary (jointly managed with Birdlife Australia). Newhaven is 350 kilometres north west of Alice Springs and borders the Great Sandy Desert. Report is here.

Textures of the Australian Bush – Sands of Angels Beach

The Doc’ parents house overlooks Angels Beach, East Ballina. Here is a selection of sands from the beach, intermixed with algae, wind and wave action, rutile, footprints and even some surf scum. Take more notice next time you walk along a beach.

Piccaninny Pleasures

Just returned from a Cape York Trip visiting the AWC Sanctuary called Piccaninny Plains. Piccaninny Plains is the name of the pastoral lease if you were wondering. Report and photos here.
