Found a pretty good site right on the edge of a glacier, if you need to build that ice skyscraper.

Has sand (with a nice little space under an otherwise-stony hillside for farming), a magma tube, HFS, a pit with lots of webs (GCS? I haven't checked..), and a short stretch of underground river. Lots of tasty hooved wildlife roaming around. There's an aboveground stream, most of it is frozen year-round, but a section does thaw in the summer, which might allow for some Fun. A central plateau which can be isolated fairly easily for ambush-free construction. Flux (limestone) which conceals one good-sized vein of bauxite. Lots of gems, lots of copper and iron, and at least samples of every kind of metal except, evidently, gold. Also no coal that I can find, and not a whole lot of aboveground trees. Full access to all other civilizations, so you can trade for the missing stuff.
I would recommend going with a five-by-seven embark and getting more ice from the glacier, or more limestone/trees to the north. Also gives you a keen place off to the east to dig out to and use as a forced wagon-path.
