Human: Please write a brief description of a strange place with a squat stone monolith with an indentation in its top and a rust-colored residue stains it. Assistant: 
The grass is flourishing here despite the apparent blight of the rest of the wood. Facing east beside the road is a squat stone monolith with an indentation in its top. Some carvings adorn its polished gray surface, and an odd rust-colored residue stains it.
