The metal and stone fish sculptures of Flying Rockfish are patterned after large-mouth bass native to Kansas rivers and streams, including the Arkansas river in downtown Wichita. The fish heads are made of Winfield limestone, formed over 200 million years ago when Kansas was covered by a shallow sea. Visible fossils -- tiny crinoids and small shells -- pepper the fish heads, serving as a record of creatures from that era. The FlyingRockfish form a school of fish swimming in the Kansas wind.
