Murchison River, Kalbarri National Park.

A broad cross section of Tumblagooda Sandstone can be seen in this image of part of a wall of the Murchison gorge.  The river, responsible for carving the gorge, can be seen in the very bottom of the image.  Over 500 million years old, the sandstone is thought to contain some of the earliest fossilised tracks of terrestrial creatures in the world.

The floodplain within the Murchison Gorge stretches out before the eye revealing a broad spectrum of ground colours and cover.

The Murchison River flows for some 650 kilometres before plunging through layers of deposited sandstone to form the Murchison Gorge, part of the Kalbarri National Park.  I’ve just spent the weekend there for the first time and I have to say it’s one of the most impresive natural parts of this country I’ve seen.  I’ll be posting quite a few photos from this region over the next few weeks and intend to return there in a month or two to explore again, in the midst of the wildflower season.
