all photos by Lance Dickey. The Clarksville Cave was incredible. And terrifying. It is just under a mile long and has a lake (resurgent sump) at one end and waterfall near the other. We checked both out and even stayed the night there.
I'll admit though, at about 3:30am I woke up in our tent and was super duper claustrophobic!
It was still an incredible trip and it was really fun to wiggle and worm through some tight spaces and wade through some deep flooded passageways too.
