The National Park Service launched a search for two women missing on what was supposed to be a backpacking trip in Denali National Park.
Abby Flantz, 25, of Gaylord, Minn., and Erica Nelson, 23, of Las Vegas, were last seen Thursday at the Savage River check station. They had planned to return Friday.
They were reported overdue Saturday when they did not report to work at the Denali Princess Wilderness Lodge, a hotel outside the park.
An air search Saturday used two helicopters and a fixed-wing aircraft. Three teams of ground searchers checked heavily wooded and vegetated sections that could not be searched from the air.
