It's been a while since I haven't created a new map as we are running out of haplogroups (or data for subclades). I thought it would be interesting to visualise the whole of haplogroup U, as this is a very ancient lineage and apparently the first to colonise Europe from c. 40,000 years ago, and Central Asia before that. Palaeolithic and Mesolithic Europe were dominated by haplogroup U (U2, U4, U5, U8 and possibly some K subclades in eastern Europe).
Haplogroup K is of course a subclade of U8, equivalent to U8b2, so there is no reason to exclude it.
Anatolia and Iran also had a very considerable percentage of haplogroup U before the Neolithic. This included U1, U3, U7 and K. Nowadays the most common type of mtDNA U across the Middle and most of Europe is the Neolithic K1a, that most likely originated in the Fertile Crescent and was diffused by the Neolithic farmers.
