I don't mind repeat postings anyway. Yours is a different source anyway.

Does sublimation not happen on Mars?

Hmm, wonder if one of our Rovers can get over there.

Yeah, I bought a timeshare there a few months back. Word to the wise, do not conduct real estate deals when you have had one Old Fashioned too many.

The ice patch is present all year round, as the temperature and pressure are not high enough to allow the frozen water to escape into the atmosphere.
Maybe one of you hard science types can tell me: wouldn't the water tend to boil or evaporate more if the pressure were low?

Still waiting for the video of our satellite blowing up a comet. I really don't expect to see anything except people clapping there hands at control center.

Where's my "water-ice sublimation rate as a function of mars atmospheric pressure and temperature" graph?
One thing we know is that the sublimation rate of CO2 is a lot higher.
To: fr_freak; CurlyDave
Maybe one of you hard science types can tell me: wouldn't the water tend to boil or evaporate more if the pressure were low? Not if the temperature is sufficiently low. This patch of ice is in a particularly cold area of mars, deep in a crater that does not get much in the way of sunlight.
The sublimation temperature of ice at typical Mars atmospheric pressure is just under 198K. There are parts of Mars that rarely get this warm.
