Yellow Springs Ohio USA Horizontal Dial 628
A 14.5 inch octagonal bronze horizontal dial on a cast iron pedestal. Dial was originally made for the present owner's great grandfather in the early 1900's. Face has Roman numerals with hour and half-hour markers. Compass rose cast in face aligns to magnetic north and stars of Big Dipper are shown. Dial was made originally for location near Northampton, Pennsylvania in early 1900's and is marked "41° LATITUDE." At present location, dial is tipped 1.2° for latitude correction. Two time arcs are shown on the dial face: "LONG DAY" arc extends from 5 AM to 7 PM; "SHORT DAY" arc extends from 7:30 AM to 4:30 PM.
 
 
Youngstown Ohio USA Equatorial Dial 720
A nearly 10 foot high steel equatorial dial with a 30 inch diameter stainless steel hour ring including cut-out diamonds for hour and half-hour marks and Roman hour numerals. The hour ring can be adjusted for EST or EDST and can be set to include longitude correction. The mild steel sculpture has naturally weathered. Located outside the YSU Ward Beecher Planetarium, the dial is dedicated to the memory of Richard Pirko, long-time planetarium engineer and show producer, whose dream was to have a sundial outside the planetarium. A nearby bronze plaque dedicates the dial.
 
 
Ypsilanti Michigan USA Horizontal Dial 346
The original horizontal dial and gnomon of 1909 was cast aluminum, very rare for a turn of the century dial, and have been assigned a safe place in history in the EMU archives. The new sundial face is weathered brass and copper. The sundial is being replaced on campus after a 30 year absence and recent rediscovery. The granite face of the sundial plinth under the metal base has directional lines indicating major cities in Michigan, Ohio, and around the United States. The original 1908 granite pedestal about 4 ft. high is still used.
 
 
Ypsilanti Michigan USA Vertical Dial 379
A 10x15 foot vertical wall dial. On a stucco wall, the dial is tile with an aluminum gnomon. This dial atop Sherzer observatory is scheduled for repainting and renumbering. A new and larger brass gnomon is in the works as well. The newer campus landmark is visible from as far away as Wasahtenaw Avenue.
