These awe-inspiring images are part of an annual celebration that showcases the very best in caving photography from around the world.
The breathtaking shots in this year’s collection include gigantic, cavernous spaces; daring abseilers; huge stalagmites and stalactites that make the humans standing next to them appear mere specs; and even galaxies of stars illuminating cave entrances.
The images selected for the annual National Speleological Society Photo Salon were announced on Thursday, June 22.
This year the salon received more than 400 individual photographs from spelunkers across the United States and Europe. (Caters News)
