Animal Pyramid by Bruce Nauman. The Art Center has an 81 acre sculpture park attached to it.

Not your run of the mill sculpture park. This one features large scale outdoor sculpture on an 81 acre site in Greenwood Park, by four artists to dramatize the beauty of the park. Bruce Nauman's Animal Pyramid is literally a stack of bronze larger that life size well-balanced caribou, elk and foxes. Like much of Nauman's work it is enigmatic but impossible to ignore. The other artists are Richard Fleischner, Mary Miss and Richard Serra.
The master plan for the park was to allow space for twelve more sculptures, but a devastating flood in 1993 caused severe structural damage to the Art Center Building. Funds had to be diverted and the current status for completion of the park is not known.
