&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The [http://www.flickr.com/photos/23526605@N00/sets/72157594241400279/ Palo Alto Urban Petroglyph Project] is a series of photographs taken on Alpine Road in Palo Alto. It appears that workers, either working below on Alpine, or up a the other end on Skyline, had a lot of amusement using up excess road tar. As a form of graffiti, it is wonderfully rich and interesting. I named my photo images based on the shapes they seemed to be to me at the time.  Whilst there is some argument in the anthropology community as to whether or not these are &amp;quot;true&amp;quot; petroglyphs, I have named them according to the best definition I had at the time.&lt;/div&gt;</summary>
