(AP) GRAND CANYON NATIONAL PARK, Ariz. - Authorities are scaling back the search for Kaitlin Anne Kenney, a Colorado woman reported missing from a private river trip in Grand Canyon National Park.
Park rangers say Kenney, 21 of Englewood, Colo., was last seen Friday night at her group's camp near Tapeats Creek on the north side of the Colorado River.
Kenney was reported missing Saturday and helicopter and ground crews searched the Tapeats and Deer Creek drainages, Surprise Valley and along the river all weekend.
Ground-based crews scoured the Tapeats Creek area again Monday. But park spokeswoman Shanna Marcak said Tuesday that with no new clues, authorities have decided to scale back the search.
Marcak says efforts will continue in a "limited mode in which rangers and pilots will continue to search for clues when in the area." She says flyers with Kenney's picture and description also remain posted at popular river trip launch and takeout points.
Kenney is described as 5 feet, 5 inches tall and 125 pounds, with brown hair and brown eyes. She was last seen wearing a tan coat and tan pants, a gray shirt, a multicolored scarf, a black knit cap and hiking boots.
