This arts complex opened with a 2,000-seat amphitheater, a 500-seat theater, and generous gallery, studio, meeting, and exhibition space. Exhibits include the restored walls of an 1864 hewn log cabin. Set in a large city park on a south-facing slope, the asymmetrical, Post-modern building had plenty of room to expand, which it did in 1992. An enlarged amphitheater features a work by Clarice Dreyer, a thicket of aspen branches in cast aluminum attached to sky-blue walls. The $10 million 1992 expansion also added a sculptural bird sanctuary by Dreyer composed of birdhouses and birdbaths decorated with flowers, foliage, and tree branches. Other public art added in 1992 includes Vito Acconci's $84,000 Ribbon Wall, an earth sculpture snaking through the new addition, and a five-acre environmental art park.
