CAMPING -- A backcountry campground near the head of Lake Chelan has been closed indefinitely because of a black bear that was lured by the taste of food and garbage left unsecured by visitors.

The National Park Service announced Thursday that Tumwater Campground, located about 12 miles from Stehekin Landing, is closed until further notice.

A bear received a "substantial food reward" when it got into a garbage can at the primitive campsite on Monday, the agency said. Though the can has been removed, the bear is expected to return to the campground to look for more food.

The nearby High Bridge Campground will also be monitored by park staff to make sure the bear does not go there in search of an easy meal.

The agency said that a camp closure of two to three weeks in generally enough to convince a bear that there is no more food there.
