These extraordinary images by Andre Ermolaev are aerial phogrpahs of rivers flowing through the beds of volcanic ash that cover much of Iceland. Sez he:
Iceland is a wonderful country; I would even say that it is a true paradise for all the photo shooting-lovers. But what has become a real discovery for me is the bird’s eye view of the rivers flowing along the black volcanic sand. It is an inexpressible combination of colors, lines, and patterns. The photo represents the mouth of the river falling into the ocean. [...] A little bit upstream there is a yellow-colored brook flowing into the river, but yellow currents fail to mix with the main water flow. One can estimate the scale judging by the car tracks that are clearly seen on the black sand. This is just a river, just a volcano, just our planet.
