This location is around the only volcano on the map. Five spires cup a volcano like they are the fingers of a hand holding it up. It has yellow desert to the north, red desert to the east and grassland to the west. For some reason the seed for this reason seems to be botched; I have tried regenerating the world but that has yet to work. Here is a picture of the region. The volcano tile is a little to the north and east in the desert. This save came from Ironhand 0.42. Easily adapted by replacing the raws.
