In Flow shows an attempt to come to an embodied understanding of the forces that have shaped the landscape of the upper Blue Mountains. Water has not only carved canyons and valleys into the sandstone it has also collaborated with geology to create the cliffs and escarpments. And yet this has been a very slow process. I have a friend who worked as a guide in the mountains and used to delight in telling tourists visiting from the United States that when the Grand Canyon was still a flat plain the geology of the upper Blue Mountains was pretty much as you see it now. The action in In Flow is an attempt to make the slowness of the change in the landscape comprehensible on a visceral level by make a very small contribution to the forces that have shaped it. This work is the ‘water’ component of the In elements series.
