A nice idea worth thinking over, but afraid the flight rule book will prohibit that. I'll look up coordinates of geysers on Mars, though (EDIT: it's Planum Australe, perhaps the next update of HEM-SAG sites will feature them - as suggested, it'll require Artlav's volcano.dll).
More threatening than a dust devil would be the Solar Proton Event.
EDIT #2: Tried south polar cap geysers, it works fine only in Ron Miller's paintings, in Orbiter it is hard to ensure good lighting at Planum Australe sites.
