The Wave Field is a land sculpture by Maya Lin, set into the University of Michigan's North Campus as a rolling grid of grassy waves. It is simple at first glance, then more interesting as you walk around it and see how the ground itself becomes the artwork.
This is a small, quiet stop rather than a marquee attraction, but it is a good one for travellers interested in public art, landscape design, or the university beyond central campus. It also gives North Campus a reason to visit that does not depend on having university business.
