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.

appearing to be some seaweed gently swaying under water, this is actually an above-water decorative grass (green foxtail) that has those fuzzy tops resembling caterpillars. this is a closeup shot (capturing 0.1 x 0.16 inches) of the seeds and fuzzies that dance in the wind atop this tall grass. the seeds can be seen as large light-green pods with dark-green stripes (like a melon), and the fuzzy strands can be seen in light-green branching off the main stem in the middle, and eventually fade to brown as they reach their end.

rarely does an insect stay put long enough for us to go through our setup process, but this large dragonfly was very trusting and didn't move while we choose a good macro lens, took light readings, test exposures, and finally this shot.

Columbines, in general, are a lovely flower coming in wide assortment of colour combinations. This giant columbine was growing all by itself and appeared very proud to be doing so well on it's own.

i love bamboo. there is just something about its form and usefulness that appeals to me. it grows quite fast and is very strong yet flexible. while traveling through various bamboo forests in China, i've seen new bamboo sprouts that were at least 4-5 meters tall.
