Generate a detailed description of a spooky scene outside a chasm with a crevice and a pond.

A narrow ledge with barely enough room to stand on stretches halfway around the interior of the pit. Though a precarious perch, the view from this ledge offers a better glimpse of the cavern down below. In one corner, a waterfall rushes out of an opening into a small sparkling pond, and in the other, a large crevice dominates the wall. Every once in a while, it appears as though something moves just inside the crevice, but it is of a mass so large, surely it is a trick of the light.
