State highway maps usually either have two full size state highway maps, one on each side. Or, they have one full state highway map on one side, and on the other side, a number of inset maps which focus in on a city, metropolitan area, or region, and quite a bit of other information (although some of this information could be on the front as well).
The way you paraphrased the question, Jocool, doesn't really make too much sense, but I get the feeling that there was information somewhere near Pierre Township about the size of it. PLSS really shouldn't have anything to do with the question. Although technically PLSS still exists if you're looking at a state highway map in one of the 30 states that uses PLSS, it is not drawn on state highway maps. If a question similar to that comes up at a competition, I would definitely ask about it.
