The interior of the cave was dark except for the small patches of light provided by the torches mounted on the wall. They each grabbed a torch from different areas in the corridor as they walked so as not to draw attention to the missing lights. With the aid of the flames, the kids could see the etched limestone walls.
“Wow,” remarked Brody. “I saw pictures of the cave but they didn’t show these marks in the walls.
“The Blue John Cavern was created thousands of years ago by two underground rivers. The rushing waters of the rivers carved the passageways and rooms of the cavern by eroding the limestone. The water left its mark by etching the walls, leaving these scalloped patterns from the wave motion,” explained Max. Brody and Emma touched the rough walls. “In some areas up ahead, the river waters churned out big rooms leaving the veins of the Blue John Fluorite exposed.”
