My daughters and I had been playing a map named Raven (named after my dog, he's a 13 year old black lab mix). We hadn't explored a whole lot, but since we'll soon have to start a new map, I went out exploring along all the roads.
To the north of the hub city is a large lake, a lot of forest land, and all the northeast area is snow. There's some scrub land in the far northwest. There's 1 crossroads. There are various ponds and a long skinny lake more like a wide river. The entire upper half of the map would be great for wilderness survival, whether you like forest or snow.
To the south of the hub city is wasteland, a little west is burning area then more snow, and there's a lot more forest area all over the south. To the east and south is scrub land and desert. All over the southern half of the map are 6 assorted towns plus crossroads. The entire lower half of the map is apparently where people lived previously. There are quite a few ponds/tiny lakes - enough so you can find water when you need it.
I didn't take the time to explore any of the many paths, but we're going to come back to this map after the next patch to see what else we can find.
