He led WDRB News down into the darkness. “That is the doorway,” stated Toomey, the park’s cave specialist, and analysis coordinator. “The cave is my workplace.”

Within the cool, damp tunnel, mined nearly a century in the past and absent any everlasting lighting, Toomey clambered down roughly eight tales of stairs earlier than reaching the cave ground. “Welcome to the cave,” he mentioned as he pointed at a close-by wall. “That is the place issues are taking place.”
