At first, my idea was to remake one of my most popular maps, Big River Wilderness. The plan changed a little along the way, and I ended up making a map of that covers about 1/4 of the area as the original. This map has plenty of opportunities to build big, with ample flat land, rivers, and mountain peaks.
