Just generated a pretty interesting map feature, that I think might be of particular interest for some folks, so just posting to share.
Basically its just two islands formed naturally from the twisting intersections of two rivers leading to a lake. Makes for pretty good natural defenses if you incorporate it by building your base entrance on the islands.
Details and screenshots below:
3x3 map in small (65x65) world
access to goblins, elves and humans
36 out of 40 megabeasts still active in world
150 years world gen
3 cavern layers
Around 25 z-levels between 1st cavern and surface
Where to find it?
Cerulean swamp (lake tile) (middle, west portion of map, below the misty steppe, next to the lakes of culmination)
Biomes:
tropical freshwater marsh (joyous wilds)
tropical freshwater marsh (mirthful)
tropical freshwater lake (untamed wilds)
Prospect reveals:
sand
tetrahedrite 38223
magnetite 24500 (just below surface)
native gold 4200
galena 3145
native silver 907
malachite 240
dolomite 46270 (just below surface)
marble 100286
microcline
orthoclase
cobaltite
gabbro
quartzite
Notes about map:
The murky pools are dry, probably because of the scorching weather. The river will drain (!!) towards the bottom left corner of the map, and eventually empty the natural river moats. However, if you dam up the bottom left corner of the river, the lake will fill up the water eventually. Tried and tested. Also, Hippos and plenty of fish. Have FUN!
