After the boiling hot mineral water oozes up from the earth, it eventually starts to cool and the mineral elements fall out of suspension. Since the edges are cooler than the middle, the sediment builds up a little perimeter wall one grain at a time. Over time, large cascading pools are created as they overflow and puddle to create more.

appearing as a beautiful iridescent wing from a magical creature, this is actually a small portion of a single grain of black sand. we were exploring a small clump of sand for a good shot, and noticed a tiny colourful spot sparkling out from one of the grains of lava rock. zooming in much more, we discovered this 'wing' shape measuring 0.0058 inches long (equivalent to the thickness of a sheet of paper). the entire grain of sand at this level of magnification, would fill 20 of these photos.

I had not seen a Bald Eagle before and certainly did not expect to see one in Indiana. I was driving along a stretch of highway with forest on both sides and where hawks are a common site. I usually scan the sky to see what might be flying around and one day I see an absolutely huge silhouette swooping down. It was far bigger than any hawk I've seen, so I pulled off the road and began to explore. Not far away, I learn that it was a Bald Eagle and it was now calmly sitting in a tree. I reposition my car to make full use of a hill, then stood on top with my tripod and longest lens to grab this shot.
