This is one of many pools of water from underground hot springs at Yellowstone. As the water spreads out at the surface, it cools and allows a variety of different algae to sustain life. In this case, the algae that survives in the hotter temperatures is blue and green, and the somewhat cooler algae appears red and orange, forming a circular rainbow pattern to mark the temperature ranges of the water.

This is a collection of some of the water drops flowing into the Yosemite Valley. It is difficult to take a bad photograph in this area, as the main valley area is surrounded with lush pines and giant cliff walls in all directions. The falls were abnormally robust this summer due to a previous heavy winter and wet spring.

I'm climbing down inside a volcano crater and am amazed with the variety of rock/soil colours that are so neatly piled about.

This is truly in the middle of nowhere and reachable only by foot (or perhaps parachute). It's hard to believe that rock could form in such fluid shapes but it sure makes for a great find for those willing to bare the elements of the desert.

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.

almost looking like the famous british breakfast omelet, this is actually an extreme closeup shot of a flower petal. more specifically, an area of 0.06 x 0.04 inches (about the thickness of a DVD) of a gladiolus bloom. i focused on the area of the petal where it transitioned from an overall pale-yellow down to it's dark-red throat. here, i discovered a layer of egg-yolk-like cells separated by clear gel-like cells which allowed me to see down to a lower layer of pale-yellow flesh riddled with tiny purple spots (averaging 1/1500 of an inch each). all-in-all, a most interesting find for the day that makes a beautiful piece of abstract art.
