Description:
Above the southwest entrance of the Chemistry-Geology Building is a vertical declining dial built by Richard L. Threet in 1979. The dial uses thin aluminum tubing as a gnomon to cast shadows on a ring of hour and half hour lines approximately 9 feet in diameter. The lines were originally painted black on the white concrete wall with only the 9 am, 12 noon, 3 pm and 6 pm lines boldly numbered. Since then the dial has lost all but the 12. DIAL DESTROYED BY BUILDING REMODELING Per Richard Threet 12/2/2006
