when a large mass of lava cools very slowly, it can create column-like fissures during it's cooling. then, over the years, water and ice push the columns apart and the outer pillars topple giving you a scene like this one. there's only a handful of places on earth where conditions were just right for these strange rock formations to form.

I planned my passage through southern Arizona when the giant saguaros would be in bloom. I always enjoy shooting flowers, but these blooms posed a new problem for me - they were all twenty to thirty feet above ground. As I hiked around exposing film on all sorts of life, I not only came across a good steep hill, but it had a large healthy cactus growing right next to it. Thanking mother nature for making this possible, I set up on the side of the hill and maxed out my largest zoom lens to capture these blooms.

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.
