YELLOWSTONE NATIONAL PARK, Wyo., Aug. 7 (UPI) -- Park officials and local authorities at Yellowstone National Park are looking for a tourist they believe crashed a drone into the iconic Grand Prismatic Spring on Saturday.
Despite personally approaching park employees in an attempt to retrieve the drone, the tourist was let go and the incident was not immediately reported. In June, the National Park Service banned flying drones in all parks and water tied into the U.S. park system.
