As Johnson explains in his photo caption, “I’ve been traveling to Jakarta for work a bit lately and I’m always looking for new places to photograph. I was inspired by some shots of this cave I found here on 500px and knew that I had to go there. This was the toughest selfie I’ve ever taken.”

Meanwhile, Derek Burdeny’s photo “Nature’s Fury” placed 3rd in the contest.
