Look how close this stuff is!

I really like this photo because it underscores an important point. These things are all around us. It's amazing to think how close our developments have come to these amazing pieces of history.
This is an example of the best case scenario. Here in Phoenix, a major road was planned to be constructed near these glyphs. While I don't know the whole story, it seems that during construction, the developer was made aware of the glyphs by a local resident. The city archeaologist got involved, and the road was diverted. Everyone loves a win-win situation. The glyphs were spared, and the road was completed. The road is a major artery here, and I drive it every day when I take my kids to school. I've been down that road literally thousands of times, and until recently I had no idea that the glyphs were there. There's a path along the fence seen in the picture. People walk on that bath, kids ride their bikes on it. I've visited the site a few times, and I've found nothing that would make me think that these glyphs are being defaced or destroyed.
Again, this is the best case scenario. I read on the Internet that glyph sites just south of Las Vegas are in danger because of the rapid growth in that area.
Phoenix is also experiencing rapid growth. In fact just a week ago in the suburb of Chandler, a wooly mammoth skeleton was unearthed at a construction site. It is my fear that in pursuit of the almighty dollar, interests will ignore these findings and bury them under whatever projects they're working on.
I'll choose the path of the optimist, and look to the example above when I see development and history collide. In the meantime, I'll keep a close eye on the sites that I know about, and get involved should I ever see a bull dozer approach. :-)
