Sheriffs at the Grand Canyon say they're not as concerned about a flood situation as they were earlier in the day. Still, dozens of people have been flown out by helicopter after an earthen dam gave way Sunday causing flooding in a side canyon. It's home to about 400 members of the Havasupai Indian tribe. Their village of Supai is on high ground and no damage is reported. But some hiking trails and footbridges were washed out and trees were uprooted. The canyon area has had as much as eight inches of rain since Friday, and there's still the danger of flash floods. About 150 people were airlifted to safety during the day, and evacuations were to continue until dark. But many residents and campers have chosen to stay put.
