Below ground caverns in Arizona wilderness, carved out by centuries of flash flood waters from rain many miles away.

Many northern states like Montana have an abundance of colourful stones delivered by glaciers long ago. These happen to be at the edge of a lake under a few inches of water. The entire beach area and bottom of the lake (as far as I could see) was covered in this manner and the stones just under the water provided great rich colour with minimal wave distortion. To be able to shoot straight down and not have any perspective in the stone pattern, I stood in the water and waited for the ripples to disappear before capturing this neat texture image.

looking quite similar to an xmas tree with ornaments and tinsel, this is actually a photograph of a hostile invasion possibly taking place in your own backyard. if you see a plant with a white or light-gray powdery substance on the top-side of its leaves, it is probably an invasion of the 'White Powdery Mildew Fungi'. many different types of these spores spread with the wind, rain, birds, and even the feet of insects, and when the right type of spore lands on a suitable plant, it quickly takes hold by rooting into the plant. it then steals nutrition from the plant to grow an outbreak of thread-like structures over the surface (seen as white rice-like chains in this photo) which eventually block the plant's photosynthesis process and kills it. when the mildew fungus is sufficiently mature, it develops new sets of spores (inside the brown raisin-like containers) to travel in the wind and repeat the cycle. each of the brown spore-sacks measure about 0.0014 inches in diameter which is the thickness of kitchen aluminum foil.
