Another Abstract from Benson Mines

This is from my first visit to Benson Mines. It is a photo of minerals leaching out of concrete. I see this frequently on old concrete. Soluble minerals dissolve when the concrete gets wet and eventually seep out through fine cracks and fissures. The patterns are often interesting.

Note that I have added a link to William Neill's  ebooks in the column on the left. I have all of his ebooks and they are excellent. Both William and Guy Tal are photographers I respect for their vision and skill.
