Create a description of a location where you are in a dreary scene outside a volcano with an obsidian ridge and a tunnel.

Your view north is partially blocked by a black obsidian ridge rising from the valley floor. Someone has laboriously chopped through the massive glassy wall, creating a tunnel which you can pass through. You can just catch a glimpse of the road north through the tunnel, where it descends into a broad grey valley, and then curves out of sight to the east. A field of frozen flows of lava stretches out to the south, covered with pools of dull yellow ash.
