Interestingly, a series of five uniform terraces extend down to the Sunken Garden area. Located in the center of each terrace are small pools that have connecting water channels that spill into each pool on the next level. So ultimately, water flows from one ornamental pool on each terrace to the next, and finally down to the reflecting octagon shaped pond in the center of the Sunken Garden, where the water is pumped back to the first terrace to begin its round again! Along the mazed walkways of The Sunken Garden are two stone garden houses financed by the North Dakota and U.S. National Homemakers' Clubs. The placement of these original houses marks the Avenues of America and Canada and both leads to their respective countries. Thousands of perennials, flowering shrubs and annuals fill the mosaic-like beds surrounding the focal pond in the Sunken Garden. Within walking distance is the Interpretive Center housing the cafe, retail store, moderate horticultural library and conservatory.
