Human: Please create a foreboding scene outside a cliff with spruce, boulders, and a rusting wheel. Assistant: 
Several ancient spruce, their roots embedded between the boulders and the sparse soil that hasn't washed down the slope, tower like guardians alongside a dark opening in the rock face. Stacked boulders topped by a flat slate slab look more man made than accidental, perhaps leftovers from a long abandoned mining operation. Jutting from a half buried rod, a rusting wheel turns with the wind.
