an assortment of brightly-coloured algae reflect in the steam rolling off a large hot spring.

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 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.

I'm hiking across the inside of a volcano crater and loving the diverse assortment of mineral colours. every few minutes it seems like i enter a new alien world with unique soil and rock types. The distant base of the clouds are over a mile in elevation, and they peak around 8,500 feet – the camera is just under 10,000 feet to capture this beautiful and unique land.

This is a close-up of Dichrolam Film - an exotic material that won awards for being one of the most innovative materials in the world. It's paper thin and made up of several hundred layers of super-thin plastics that diffract and filter light into different colours depending on the viewing angle.

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