vast amounts of water flowing over Horseshoe Falls (Canadian side of Niagara Falls)

although passing for the scales on a blue dragon, this is actually an extreme close-up photo of the iridescent stripe on the wing of a Mallard Duck. the feather starts off with a main shaft (or quill) with hundreds of branches (barbs) protruding from the side. zooming in on one of these barbs, there are again hundreds of protruding tiny branches (barbules) on each barb. this photo captures approximately 4 of these barbules and their scale-like shapes. each of these 'squares' measure around 0.0012 inches across (less than the thickness of aluminum foil).

although usually a moisture-loving plant, i found this one in Arizona. i think its roots must have tapped a nice hidden water supply.

I'm precariously hanging over a sheer cliff to capture a straight-down perspective of the ocean waters below. With my assistant faithfully grasping my belt and a small nearby tree, i was able to get the camera gear over the edge enough to watch for the best mixture of rock and swirling waves.
