Lawn Hill is certainly scenic. Sandstone gorges and spring-fed rivers lined with fig trees (Ficus racemosa), tall paperbarks, cabbage palms (Livistona mariae rigida) and pandanas, views from the stacks and lookouts, entertaining canoeists, birds, reflections, interesting walks, aboriginal heritage, fish, wildflowers, freshwater crocodiles, turtles, beautiful weather - what more could you want.
One intriguing thing was the tufa. It looks and feels like stone and is wrapped around tree trunks and rocks in parts of the river bed. Apparently it's calcium carbonate deposited due to high water turbulence caused by rapids (a greater level of carbon dioxide out-gassing). I'm not a chemist but I am good at reading pamphlets and info boards.
