Waves of distortion in the Valley

Shot this after climbing a very high rocky hill on the edge of Hustai Valley, Mongolia. What's especially interesting is that in a 360 degree sweep around there's not a man made object to be seen. Cascades of soft sounds sweep through the valley. The air is full of windy wisps of grasses and a hollow sound that's much like listen for the ocean in a shell. At this time of year in the cold of late march there were no insects. An occasional eagle and hawk can be heard echoing through the valley. The wind that sporadically picks up speed leaves the imprint of it's path with waves of distortion that twists and vibrates the vegetation.
