The history of Barton County, from unbroken grassland to modern wind turbines, is the latest subject for Great Bend artist Chet Cale.A series of bas relief panels by the sculptor is going up at the Barton County Historical Society. Bev Komarek, executive director of the historical society, said the artwork – 8 feet wide and 6 feet high – will be the focal point of the museum’s new recognition wall. Names of significant donors will frame the artwork.The visual history of Barton County starts on the right-hand side, like a map of Kansas where the time line starts in the east and moves west.
