asset waterfall "Mountain waterfall" complexity=7
// a mountain waterfall: a broad faceted cliff striped with strata and capped with moss, a stream
// running over the top into a curling foam lip, a fanning sheet of falling water, foam heaped where
// it lands, a round plunge pool ringed with boulders; drops fall, spray bursts and mist rises
