coming down off the mountain just in time to witness the sun setting and the nearby cloud-line lighting up in pink.

I'm certainly not a marine biologist, but am informed that this is a 'Dactylometra Quinquecirrha' type jellyfish, so I'll take their word for it. Their tentacles are covered with stinging cells that attach themselves to anything that touches them and injects a venom into it's prey. Fortunately I didn't get the opportunity to experience this in action even though I'm told it's not fatal. My biggest problem capturing this image is that there is absolutely nothing stable to attach a camera to underwater. Tripods are useless, I'm moving, the camera is moving, the sea creatures are moving, all at different rhythms (guess I didn't need to bring the cable release). All in all, this was probably the most serene and beautiful creature I've ever witnessed; it's pulsating motions and delicate nature were extremely enjoyable.

yes, this is real. i was hiking through a desert (with a load of camera gear of course) and saw this little cactus growing on top of a rock. it was too unique and charming to pass by without taking this photo opportunity.

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.

another spectacular view of Waimea canyon. The lush vegetation and diverse soil colours make for some very nice canyon photos.
