Human: Generate for me a description of a chilling scene outside a canyon with cracks and pebbles. Assistant: 
Rising higher and higher, the walls of the canyon leave only a small sliver of the night sky visible overhead. Falling pebbles create a constant background of echoes that disrupt a continuous chattering noise emanating from cracks in the northeast face of the rock outcrop. To the south, the steep southern wall of the canyon can be seen as a towering black void against the silver night sky.
