7 Very Tall Things in Very Flat North Dakota
North Dakota is not quite the flattest state in the U.S., but it's pretty close. (In one analysis, it placed third, after Illinois and Florida.) During the last Ice Age, glaciers moving across the terrain had a planing effect on the land, dropping sediment that filled in any valleys, creating sprawling prairies and open, big skies. These large expanses are home to more than a few sky-high structures, both natural and human-made. From rocky peaks and multi-ton animal statues to one of the tallest buildings in the world, these are some of the most impressive structures that North Dakota has to offer.
