Sister says hiker still missing in Grand Canyon flash flood amid intense search

SUPAI, Ariz. (AP) — Search and rescue crews at Grand Canyon National Park are searching for an Arizona woman nearly two days after she was swept into a creek during a flash flood. A sister of the hiker said Saturday that rescue crews are hard at work and have not yet located 33-year-old Chenoa Nickerson. The National Guard has been called in to help evacuate other hikers. The National Park Service says Nickerson was swept away into Havasu Creek Thursday about a half-mile from its intersection with the Colorado River. The park service says the flooding trapped several hikers around a waterfall called Beaver Falls on the Havasupai reservation before they were helped to safety.
