Gilbert, Arizona

Some 200 million years ago, the area was a vast sea, which is why you can find seashells all over the Sonoran Desert, Utah and other places in the West. American Indians also traded for seashells from coastal tribes so they could turn the shells into jewelry. These are mostly found in prehistoric ruins.
