"SIERRA VISTA, Ariz. — It's easy to spot the San Pedro River from the air; just look for the cottonwood trees outlining its banks.
The bright green forest persists even at the height of Arizona's dry season in June, when most of the river doesn't have any water. But summer monsoons this month bring waves of water up to a dozen feet tall.
The path of past floods is obvious from 12,000 feet in the air — a wide strip of limestone sand winds through the trees, as though a bulldozer cleared the way."
