Where can I find out about the finds at Calico Hills in the Mohave Desert?

Dr. dig responds:
I think the best place to start is to contact the Bureau of Land Management, on the web at: www.blm.gov

I have not come up with any recent news that I could easily put into your hands. For online images of petroglyphs from Clark County you can go to: www.geocities.com/RainForest/Vines/7608/petroglyphs/page1.html
