Soletto set to 210,000 mk, all cities at 10 to 13km's high. 1 mine at altitude of 7km's as a flood canary and the amount of water left on the planet Mars is insufficient to flood the entire planet beyond 6.5 km's. But yet it floods and everyone on the surface is "drowned" to death - unable to breath, 'kin snuffed it. Kicked the bucket, run down the curtain and gone to join the choir invisible, the population of Mars is now an ex-population, gone to join the 4 previous ex-populatios of Mars.
