Photographer's Note

For those knowing that I have been last weekend at the Mojave National Preserve this image must be a real surprise and yet it was taken there. Mojave isn’t just a plain desert. It has its own particularities and one of them is a region called the Cinder Cones. As the name already suggests it has something to do with volcanic activity. The last activity was somewhat 10,000 years ago and left behind what we call a Lava Tube. A very hot and highly liquid lava flow created a subterranean channel and once the lava receded it left the vault behind. Many many years later wind and water eroded several holes into the ceiling creating a comfortable entrance for adventurous humans and some smaller holes for the sunlight.

I spend the weekend at the Mojave with Steve and he was actually the one that discovered the tube. There we went with our cameras, tripods, flashlights, and high spirits. The team effort was perfect by combining our flashlights. This shot has the build-in flashlight of my camera to light up the foreground, Steve’s slave sensed flashlights behind the rock in the background, the regular light in my hand illuminating part of the rocks above us and finally the fading daylight shining through the hole in the ceiling.

This place was so fascinating that we spent more than 2 hours in the tube. We missed the sunset out there and we even returned next day to catch the sunbeam coming through the ceiling and leaving a trace of sunray through the dust enriched air. This will be something for a next post.
