This image is posted here in response to Norm's Question of the Day on Realneo [1] - the question being what caused the stains on the rock formations in Dulce. I had my opinions - mainly relying on water and organic growth - but before I responded to Norm I thought it purdent to go to Google Images and look for other examples and explainations. I found this spectacular image of rock stains in Yosemite on Flicker. The image belongs to Rigphoto and I link to it here [2].
