JACOB LAKE, Ariz. (AP) — Visitors and staff at two national parks in the U.S. West have been evacuated because of wildfires. Black Canyon of the Gunnison National Park, about 260 miles (418 kilometers) southwest of Denver, closed Thursday morning after lighting sparked blazes on both rims, the park said. The wildfire on the South Rim has burned 2.5 square miles (6.5 square kilometers), with no containment of the perimeter.
