According to Mammoth Cave National Park, the world’s longest cave system has added 8 miles (13 kilometers) to its length. The additional mileage was mapped and documented by the Cave Research Foundation, as per Mammoth Cave National Park.

It brings the total length of the cave system in south-central Kentucky to 420 miles (676 kilometers), officials said. The announcement highlighted the park’s recognition of National Day of Service and its longtime partnership with the nonprofit foundation. Volunteers with the foundation have worked with the park for decades to map and document Mammoth Cave.

Rick Toomey, Cave Resource Management Specialist at the park said that the  Cave Research Foundation is fundamentally the reason that Mammoth Cave is recognized as the world’s longest cave.
