CASPER, Wyo. (AP) — Concerns about bears are prompting federal officials to close the upper loop of the Prior Flat Campground in the Shirley Mountains, about 30 miles northwest of Medicine Bow.

The Bureau of Land Management said Friday that the closure comes after reports that a black bear has been getting into garbage cans in the campground.

The BLM says the closure is expected to last through this weekend, or until state wardens can capture and relocate the bear.

The upper loop closure affects four of the nine developed campsites in the Prior Flat Campground. The others will stay open.
