There are no such maps, normally, where you don`t see tundra + ice tile combinations together with deserts and peaks and what else not, that really is not the most convenient terrain to settle in. Then again, quite often such terrain offers some resources, that are rarely found anywhere else. The question is - is a junk city worth the cost for some, perhaps, irrelevant resources?
if silver + 1 food resource or 2 furs + 1 food resource, I settle asap for short term.
if not - after blocking, in the end of the queue(around biology or such); hopefully breed some barbarians and raze their cities from time to time for some cash/unlock he/etc.
