Been hung up, but still mapmaking.
The above connects the recent work on the Dneiper's course with that I did in December of 2022, when I started mapping the Dneiper from the bottom left of this map down to the Black Sea. From here, I continue to move southeast to the Black and across the Sea of Azov, I think completing the Crimea east peninsula, the Kerch, showing the strait between it and the Taman Peninsula of what's called Kubanistan, in modern Russia.
The "swamp" land shown is moderate bogland, easily crossed on foot though damp and spongy, and subject to flooding in the late spring. It is a topography that hasn't existed since the early 20th century, before World War II, so the Germans did not need to contend with it; of course this isn't what the region looks like now, it's a reservoir. It makes a natural boundary between lands controlled by the Turks south of Kiyev and the Zaporozhian Sich, or cossacks, enabling the latter to strike along routes through the soft country that they know to be firm enough, in some seasons, for their horses. This makes it hard to defend the lands of Krivassa against raiders, which makes for a good set-up in any campaign. Obviously, such a wide, treeless soft-bottomed open ground, braided with hundreds of tiny brooks not shown on the map, can be imported into anyone's personally generated setting.
