The lower Finke Gorge is very different to the deeply trenched upper Finke and Ellery Gorges.  Here, it cuts through thinly bedded and gently dipping sedimentary rocks, creating a wide valley.  The riverbed is about 300 m wide and is flanked by alluvial fan, floodplain and aeolian deposits.  The lines of trees in the channel (centre right) indicate linear bars.
