The northwest corner of Maplehurst lies in the hilly terminal moraine that runs from Westboro through Perkinstown and Lublin. That land is choppy because it has had only about 15,000 years to level out since it was dumped by the last glacier. Within that northwest moraine are some ice-walled lake plains, which are fairly level and farmable. Outside Maplehurst's northwest corner, most of the town is fairly flat, covered with till deposited by some earlier glacier at an unknown date, with much more time to erode and level out. The Black River and smaller streams have cut channels through that flat area. thumb|upright=1.2|Glacial landforms of Taylor County.
