Hellas honeycomb terrain recently interpreted to form by salt or ice diapirism. We explore the parameter space in which salt/ice diapirism is predicted to occur. Results: Diapirism requires 0.1–1 km ice, 0.6–3.1 km gypsum or kieserite, or 1.0–3.1 km halite thickness. On basis of the large salt thicknesses required, ice diapirism is more likely. Ice could be remnant of frozen ocean (warm Mars) or glacial flow into Hellas (cold climate).
