Human: Produce a detailed written description of a wild scene outside a road on a mountainside with a bridge, roadbed, cataract, and brick parapet. Assistant: 
A spate of water roars down the mountainside with deafening noise and drenching mist, rushing under a stone bridge that carries the road across its path. A high brick parapet on the side toward the cataract screens the roadbed from the worst of the spray.
