SPRINGDALE, UT (Associated Press) – A woman died and a man was rescued and treated for hypothermia after they were caught in extreme cold weather while hiking in Utah’s Zion National Park.

The National Park Service says the married couple were on a permitted, 16-mile hike through an known as the Narrows on Tuesday and Wednesday. The woman, 31, and the man, 33, were not identified.

The park’s rescue team responded Wednesday morning and found the man on a trail being helped by other hikers and transported him to the Zion Emergency Operations Center for treatment.

Rescuers administered emergency aid to the woman but determined she had died.
