ANCHORAGE - The National Park Service has closed part of Gates of the Arctic National Park in response to a bear mauling.
A woman was attacked at her camp site in the Okokmilaga River drainage. The park service said her injuries were not life-threatening.
Gates of the Arctic covers 13,238 square miles - about the size of Switzerland - and consists mostly of portions of the Brooks Range.
The area closed Thursday is west of Anaktuvuk Pass.
Park Service officials said the bear probably was a grizzly.
The woman was part of a group of seven hikers. Park service officials could not confirm her name or hometown.
The Okokmilaga drainage is sparsely used and the closure is not expected to displace other visitors.
