We call it a dust storm swirling in between the mountains as we make our way to Glenorchy for a horseride but our guide corrects days of incorrect nomenclature and tells us it is rock flour. This explains not only the swirling white but also the amazing turquoise color of the lakes and rivers. When the flour is suspended in water it results in this color. Rock flour comes from the grinding of rock by glaciers. It seems like all roads lead to glaciers in this place. Our horse ride is inspiring. One of our horses is an actor (Fellowship of the Ring) and another a model (Australian Vogue). My horse's ears give away that his granddaddy was a mule. We have something in common (snicker). That mule took me higher than I have been in a long while and we never left the valley. What the hell am I doing with my life not making this a regular part of it?
