Searchers have found a note left by a missing woman in the North Cascades National Park.

Ranger Kinsey Shilling said the note says she's out of food and headed downstream, following a creek.

Searchers were focusing in that area, where they also found a water bottle, apparently belonging to Mary Hyde Wingfield.

The car belonging to the 31-year-old Seattle woman was found Thursday night at the trailhead for the Stetattle Creek Trail near Diablo dam.

Wingfield failed to return Sunday from a weekend camping trip.

The search was being conducted by park rangers and Whatcom County sheriff's deputies.
