I'm kind of curious if anyone knows why the moisture would migrate to the polar regions of the planet.

Less centrifugal force?

just my guess......given Mars position as relates to the Sun, sunlight must travel thru more atmosphere at the N and S poles, which decreases the heat reaching the surface, compared to its equator. Same reason the Earth's warmest temps are on the equator, LOL

Dynamic cooling. The entire planet undergoes periodic cooling and warming but the extreme poles are relatively stable. The water in temperate regions tends to evaporate and enter the atmosphere and evenly precipitate all over the planet. The water in the polar extremes tends to remain there once deposited. After the atmosphere was dissipated, the resulting deep freeze kept the status quo with the majority of water located at the poles.

Because one million years ago, the president of the United States of Mars, Sal Gore, convinced the entire population of Mars that it was too warm on the planet and inacted scientific programs to 'fix' the planet. :) The road to an arid, un-populated planet is paved with good intentions.

[Alas Babylon!]

Actually, the water didn't migrate to the poles, but the water that was at the poles (assuming there was water everywhere) froze. The water elsewhere evaporated out into space, leaving only the poles with lots of water--in frozen form.

Just as a knee-jerk reaction, I'd bet that a lot of it was moved there via rain weather patterns and froze....or was turned to ice by the cold, like our polar caps....and the liquid that was in the temperate regions bled off into space and/or was absorbed into the ground.

I could easily be way wrong.

It would probably condense there because of the cooler temperatures.
