Karl in front of one of the pools at the River Pirai. Karl was asking me why I didn't get the shot of him throwing the rock in the water. Uhm, the camera's slower than I thought? Throw another rock. He was worried he was going to hit a fishie. There aren't any fish in these pools, there's nothing for them to eat when the rest of the river dries up, from what I understand.
Karl in front of one of the sorting towers. These are used to sort different sizes of river rocks that become very colorful gravel and sand, with is just basic sand. Lots of sand. Everywhere, all the time, it's like a desert here, but it's the rain forest.
