Z Bend

The Z Bend is a geological rarity where a river takes a 90° turn owing to a horizontal fault in the underlying rock.  The fault can be seen trailing off to the left in this image (I’ll post an up close of it tomorrow).  The fault allows water to erode out more easily the rock underneath, causing the water to take the path of least resistance and thus, a right hand turn.

Murchison Gorge, Kalbarri National Park.
