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.

I was camping out on one of the lower peaks (about 8500 feet) in the Andes Mountains. It was a wet and somewhat tropical area and had a light rain most of the night. As daylight started making itself known, the remaining rain clouds started dissipating and swirling about the neighboring peaks. Once again, I grabbed my camera gear and prepared for a moody shot. The sunlight was peaking out here and there, clouds blowing by and changing each second, I just had to wait for everything to come into balance and squeeze the shutter's release cable. The dark neighboring mountain peak intertwined with scattering clouds created a mysterious and suspenseful image, expressing the drama in the air this morning.

glass tulips illuminated with various neon lights would certainly make a wonderful piece of contemporary art, but this is actually a closeup photo of a Grecian Windflower. in between the bumpy center cone and the outer petals, is a ring of many stamen with short filaments. zooming in extra tight on the area where the anthers (top part resembling mini-tulips) connect with the filaments (supporting stems), and adding in a micro-spotlight to make everything sparkle, you then get a shot like this. each filament (stems seen at the bottom) measures around 0.0062 inches in diameter which is a tad thinner than a bristle on a toothbrush.

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.

The minerals in the lake water cause it to be abnormally blue and clear. I can see straight to the bottom where lie many fallen trees that seem not to decay or dirty the water. As I hiked around these lakes, I really enjoyed the wavy branches that overhung the water like this one. The colours and shapes complemented each other quite well.
