Human: Produce a detailed written description of a scene outside a wilderness lake with a rock and water. Assistant: 
The chilly water in the shallows of this subterranean lake is crystal clear, showing the silted bottom. It looks only knee deep. Drops of condensation occasionally plummet from somewhere unseen, far up above. A large rock rises up out of the water to the east, making straight travel impossible. The lake stretches out to the southeast, around the rock while the gravelly floor rises up to the west.
