Well Water Likely Available Across Mars (behindtheblack.com)
schwit1 quotes Behind the Black: A science paper released today and available for download [pdf] cites evidence from about two dozen deep impact craters located from the equator to 37 degrees north latitude that Mars has a ground ice table at an elevation that also corresponds to other shoreline features.
The paper calls this evidence of "planet-wide groundwater" with elevations that "notably coincide with the elevation of some ocean shorelines proposed by previous authors."
Science writer Robert Zimmerman adds that "The evidence suggests that this deep groundwater water table (as ice) almost certainly still exists at all latitudes, though almost entirely underground...
"All you will have to do is dig a well..."

TFA says the ground-ice table is 4.0-4.8km below the surface. That'd make the well quite deep -- we did manage a 12km hole on Earth but it took multiple decades to dig. Doing so without means to ship all the equipment might be a wee bit hard.
And if you dig that deep, you might reach Hidden Fun Stuff.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
