Exploration of the Unknown
You never know what you’re going to discover in a cave. It’s not like a mountain that you can see, you know is there, you know how tall it is, you know where the summit is.
In a cave, it’s all hidden. You don’t know what’s around that next corner. You don’t know how deep that pit is. Even when you’re at the very bottom depths of a cave, you don’t know if that’s the end. There could be more passage just beyond that rock wall.
That’s what I love about caving. The exploration of the unknown.
