I wish I spent more time with this scene. I ended up liking the image, but at the time it was shot, I was considering it as only a test shot. I ended up only taking a couple of images before moving a few miles down the road where the clouds and weather appeared more dynamic. Either way, here is a White Tank Granite garden from Joshua Tree NP.
White tank boulders like these are caused by a process called intrusion. Magma was pushed up from deep inside the earth into overlying rock. It cooled and hardened and was exposed after erosion. Geologists think these rocks were intruded about 135-155 million years ago–when dino’s roamed.
Shot with a Nikon D700, 12-24 f2.8 lens, at f11, and at 1/320 of a second.
