Wyoming woman drowns in Yellowstone backcountry

YELLOWSTONE NATIONAL PARK, Wyo. (AP) — A 30-year-old woman has drowned in a backcountry river in the southwest corner of Yellowstone National Park in Wyoming.

The National Park Service says Heidi Llewellyn Smith, of Jackson, drowned Thursday in the Bechler River near a backcountry campsite.

She was one of a party of four staying at the Bechler Ford campsite.

The Park Service says the woman told other that she felt ill and went swimming. A friend later found her under four feet of water against a log.

Smith was declared dead at the scene.

The incident remains under investigation.

It is the first accidental death in the park this year, and the first drowning since September 2007.
