Given the temperature and pressure of Mars' atmosphere, "permafrost" might be a better comparison.

From TFA: "It represents less than one percent of all known water ice on Mars..."

This should be enough for a colony though. With a recycling program it would probably last indefinitely. Much better than bringing the water from Earth.

There is a sentence that seems to imply that the frozen status implies there is no life. I'm not so sure we can be sure of that. There are microbes on Earth that basically live in virtually frozen environments. (All you need are moments when the water is liquid.)

Was intrigued by this comment so I looked it up.
North and South America have a surface area of about 42.55 million sq km or 4.58x10^14 sq ft (1 foot deep water is obviously 4.58x10^14 cubic feet).
Lake Superior has a volume of 12,100 cubic km or 4.2x10^14 cubic feet.
That's unbelievable!
