This fascinating art installation takes the viewer through four eras in the history of the plains. "The Life Before Man: Avonlea Under the Sea" exhibit is a wrap around mural with life-sized marine reptiles that lived in the sea which occupied the area of Avonlea 60 million years ago. A tipi ring exhibit includes a breath-taking 16' high diorama of the Dirt Hills and ceremonial circle overlooking the "living sky" of the Missouri Coteau with a Golden Eagle gliding overhead.
