That bridge is amazing. We have a thing called devils bathtub over here. I just saw it yesterday. It is where water coming through the rocks from 2 different directions comes together and goes straight down through the rocks toward the center of the earth. If you try to swim in it, you go straight down to your death. The rocks combined with the downward force make it impossible to climb out. I stood above it yesterday and took a few pics. Just thought I'd share it with you.
