Q: Story highlights Tourist said to have crashed drone into Grand Prismatic Spring 
  
 Park officials not sure if drone damaged the spring or if it needs to be recovered 
  
 National Park Service banned drones in its parks in June 
  
 Authorities at Yellowstone National Park are investigating reports that a tourist crashed a drone into the Grand Prismatic Spring, the park's largest hot spring, on Saturday. 
  
 The tourist approached a park employee about getting the drone back after losing it in the almost 200-feet deep hot spring. The employee let the tourist go without initially reporting the incident to authorities. 
  
 "I don't think the person who they spoke with realized that drones couldn't be flown in the park or the implications of what they were being told," Amy Bartlett, spokesperson for Yellowstone National Park, told CNN. 
  
 Drones are banned in national parks. The National Park Service announced in June that it was prohibiting unmanned aircraft from all park service-controlled lands and waters, totaling about 84 million acres throughout the country. 
  
 Park rangers have not yet spoken to the drone's operator and are still trying to determine if they can even track that person down. 
  
 "The technology certainly has been around for a while, but this is the year that the problem has seemed to come to light for us," Bartlett said. 
  
 Park rangers have not determined if the drone damaged the spring and if it's necessary to recover it. 
  
 This is the latest in a string of recent drone incidents in national parks and beyond. 
  
 Visitors watching the sunset over the Grand Canyon were interrupted by a loud drone in April. And volunteers reported that a herd of bighorn sheep at Zion National Park in Utah scattered after being harassed by a drone. 
  
 Also, a Seattle woman called police in June to report a peeping Tom drone. The drone was hovering outside of her high-rise window, and the woman saw operators on the ground below with camera equipment. 
  
 The drone operators insist that they were not spying on the woman, but rather her view. They were working on plans for a new building. 
  
 Police said as long as the drone was flying in a public space, there was little that they could do. ||||| Lobby > Exhibits > Hot Water Treasures > Types of Thermal Features > Hot Springs > Grand Prismatic Spring 
  
 Grand Prismatic Spring 
  
 Grand Prismatic Spring, located in Midway Geyser Basin, has the distinction of being the park’s largest hot spring. It measures approximately 370 feet (112.8 m) in diameter and is over 121 feet (37 m) deep. A description of this spring by fur trapper Osborne Russell in 1839 also makes it the earliest described thermal feature in Yellowstone that is definitely identifiable. 
  
 Next: Morning Glory Pool ||||| A tourist seeking to take pictures of Yellowstone National Park crashed a camera-equipped drone into its largest hot spring, possibly damaging the prized geothermal feature, a park official said on Wednesday. 
  
 The incident follows the crash earlier this summer of a drone into a marina at Yellowstone Lake and a string of radio-controlled aircraft violations at Grand Teton National Park in Wyoming. 
  
 The National Park Service in June announced a ban on so-called unmanned aerial vehicles, but officials say premier national parks in the U.S. West are reporting a sharp rise in the number of drones buzzing bison and boaters. 
  
 It was not clear if the drone that crashed Grand Prismatic Spring on Saturday and sank into its depths would damage the geothermal feature, park spokesman Al Nash said, and officials were still trying to decide whether to remove it. 
  
 "What we have to determine is whether the presence of this radio-controlled recreational aircraft poses a threat to that unique resource," Nash said of the Grand Prismatic, the third-largest hot spring in the world and a top attraction for the roughly 3 million visitors who flock to Yellowstone each year. 
  
 The park is puzzling over how to find the drone and extract it without damaging the hot spring, which is 370 feet in diameter, more than 121 feet deep and known for its brilliant colors caused by bacteria and minerals in the water. 
  
 The desire by some visitors to capture and post online footage of wildlife and scenic views must be weighed against public safety, protection of natural resources and complaints by an increasing number of visitors who say low-flying drones have marred their experience at Yellowstone, Nash said. 
  
 Drones are not the first challenge affecting natural resources at a park that spans parts of Wyoming, Montana and Idaho. Visitors in decades past threw coins in water features. 
  
 Fishing Cone Geyser on the edge of Yellowstone Lake was a popular catch-and-cook site for anglers. 
  
 “People would stand on it with a fishing pole, catch a fish and then drop that fish into the thermal feature where it would cook,” said Nash. 
  
 He added: “Once it was determined there was arsenic in the geyser water, that practice stopped.”

A: 
It's been a rough summer for Yellowstone. First, one of the national park's roads was closed in July because it was melting—now a tourist trying to score some pictures with his drone has accidentally crashed it into one of the area's most famous hot springs, reports Reuters. It's unclear whether Grand Prismatic Spring—the third-largest hot spring in the world, according to the Yellowstone website—was damaged in the accident last Saturday. The tourist was the one who reported the crash, asking a park employee if it would be possible to retrieve it, notes CNN. Visitors have complained of an increase in low-flying drones at Yellowstone, a park spokesman tells Reuters, even though the National Park Service banned "unmanned aerial vehicles" in June. A drone slammed into a marina at Yellowstone Lake earlier this summer, and Grand Teton National Park has also been riddled with the remote-controlled robots. Now park officials have to weigh whether it's worth it to dig out this downed drone from the 121-foot-deep Grand Prismatic, possibly marring the hot spring, or just to let the machine rest in peace in the multicolored bacterial waters. "What we have to determine is whether (it) poses a threat to that unique resource," the park spokesman tells Reuters. (In New York last month, a man was arrested for filming windows of medical rooms with his drone.)
