The search continues Tuesday for a Vancouver woman who hasn't been seen since Sunday when she left on a spiritual quest in a southwest Washington forest wearing no clothes.

The Skamania County sheriff's office says searchers with dogs searched until dark Monday in the Canyon Creek area of the Gifford Pinchot National Forest, which is about 60 miles northeast of Portland. The area is steep with heavy timber and brush.

The sheriff's office says 19-year-old Maureen Kelly of Vancouver was reported overdue by a friend early Monday when she failed to return to the Canyon Creek Campground.

Kelly left about 5 p.m. Sunday wearing only a fanny pack with a compass and a knife.

Search operations have been set up at the Forest Service Chelatchie Prairie facility in Ambo.

The conditions in the forest are far from ideal. Another camper told Fox 12 Oregon that there are wild animals like mountain lions and bears as well as landsides.

"Where she entered the creek is amazingly steep. It's called Canyon Creek Campground for a reason," said Sharon Ward, with Pacific Crest Search Dogs. "It's very, very steep. So how she got down there barefoot is a wonder. And how she came up out of the bottom is a wonder."
