If you are heading to the Grand Canyon on Monday, be aware National Park Service fire managers will begin pile burns along Highway 64 on the South Rim. Hand piles composed of woody debris are located along the Highway 64 corridor, north of the South Entrance Station and along Desert View Drive. Fire managers plan to continue igniting piles over the next several weeks when conditions are suitable to meet management objectives. Prior to implementing the burns, fire managers will evaluate current conditions and will only begin ignition if the prescribed fire conditions are within allowable environmental parameters. Smoke will be visible within the area and traffic signs will be posted along the roadway advising visitors of the operations. If traveling along Highway 64, visitors are asked to be prepared for slower traffic and minor delays within the area of the pile burns.
