Campers, hikers and other recreationists will be barred from parts of national forest in Arizona this summer, forcing many to change their outdoor plans for Memorial Day weekend. Six large swaths of the Coconino National Forest will temporarily close to the public on Wednesday as authorities work to prevent wildfires. The forest closures will also shut down 10 Forest Service campgrounds — including Fossil Creek near Camp Verde — and a number of trails and roads. Brady Smith, a spokesman with the Forest Service, told KTAR News 92.3 FM that everyone who paid for a reservation at Fossil Creek will be refunded and once the campground opens back up, they will have a chance to reschedule.
