Underground Cavern Map
ChatGPT (DALL·E)A GPT Image 2 prompt for an underground cavern system map in top-down cross-section — a central cavern with a subterranean river and waterfall, stalactites in the north, crystal formations in the south, a central pit with depth hatch, mine-cart rails, and a blank label area in ink on aged grey parchment.

Prompt
An underground cavern system map drawn in top-down cross-section view, a network of tunnels branching from a central cavern, the main cavern large and irregular with a subterranean river flowing through it drawn in pale blue with a ripple pattern, a waterfall dropping from a higher passage on the east side drawn as parallel blue lines, a cluster of stalactites marked as small triangles hanging from the cavern ceiling in the north chamber, a narrow passage to the south leading to a smaller dry chamber with drawn crystal formations as small geometric gems, a pit in the centre drawn as a dark circle with a depth-marking cross-hatch, three tiny drawn mine-cart rails as parallel lines leading from a tunnel entrance at the top, a small blank rectangular area in the main cavern for a label, no text, no letters, no room names, hand-drawn cartography style with ink linework on aged grey parchment

How to use this prompt
"Top-down cross-section view" is the phrase that tells DALL-E to draw the cave system as a map rather than a 3D cave scene — without it, DALL-E tends to render an atmospheric underground vista. The subterranean river and waterfall give the cavern spatial logic, and naming the waterfall as "parallel blue lines" tells DALL-E the cartographic symbol to use rather than attempting a rendered waterfall. The central pit drawn as "a dark circle with a depth-marking cross-hatch" is the hazard anchor, and the cross-hatch convention is what makes it read as a pit rather than a pool. The mine-cart rails imply the cavern was once worked, adding narrative depth.
Variations to try
- Add a lava chamber in glowing orange-red at the deepest point with heat-haze lines for a volcanic cavern
- Replace the crystals with a fungal forest drawn as small mushroom icons for an underdark ecosystem map
