Rock Wall

This is part of an outside wall of a building on 1st Avenue. I've walked by this particular wall many times, but I'd never actually stopped to notice it was covered in pretty rocks before. Gosh, I'm so observant.

When I took this photo, an employee who works in the building walked by. She looked at me curiously, so I said, "I'm just taking pictures of the wall." The employee said, "Okay." And that was that.
