Windsor Connecticut USA Equatorial Dial Dial 211
Equatorial dial about 5 ft. diameter made of brass and stainless steel The analemma is incorporated into the gnomon compensating for equation of time. Equatorial ring is rotated to compensate for difference in longitude to time zone. Designed and built by Physics/Astor Dept, University of Calgary, Alberta Canada. Dial sits atop a stone plinth marked with Keller's laws.
 
 
Washington District of Columbia USA Horizontal Dial Dial 210
Circular horizontal dial 20 in. diameter cast in bronze. Has Roman numerals at hours and 15 minute marks. Gnomon missing from dial, but kept by groundskeeper, as it will not stay in place. Was temporarily re-installed for the NASS tour in 1995. The dial is modern, honoring George Donald Meid for service to the National Academy. Dial is mounted atop a concrerte cylindrical post.
 
 
Washington District of Columbia USA Horizontal Dial Dial 208
Large, ground level horizontal dial 16 ft. in diameter with 49 in high stepped hollow painted-green metal gnomon that is 5 ft 16 in long. Roman hour numerals with hour lines from 4:30 AM to 9:30 PM. Gnomon structure recalls the much larger Indian observatory dials. An appropriate poetic passage, once bolted to the gnomon, has disappeared.
 
 
Washington District of Columbia USA Vertical Dial Dial 207
Vertical bronze dial with Arabic numerals and long cast sunburst gnomon. On oblong sandstone. Dial is 60-80 feet up on an octagonal power plant smokestack. It is difficult to read, but safe from vandalism. School dated 1928. Similar to Eastern High School (#202).
 
 
Washington District of Columbia USA Vertical Dial Dial 206
Sandstone Vertical declining dial, with gnomon offset to account for it. Above doors to rear terrace of admissions building. Arabic hour numerals with half hour lines. Carved hourglasses on both sides frame the dial. Brass compass rose set into the brick terrace below suggests the general alignment of both house and dial.
 
 
Washington District of Columbia USA Armillary Sphere Dial 205
Very nicely armillary sphere about 3 ft. diameter, with equatorial, meridional and hour circles. Roman hour numerals from 5 AM to 7 PM. One of Washington DC's cleanest examples of a working armillary sphere. Erected by the Georgetown Garden Club in 1956 in tribute to Sarah Louisa Rittenhouse. Dial is placed atop a sandstone pillar.
 
 
Washington District of Columbia USA Horizontal Dial Dial 204
Horizontal dial about 16 inch square made of bronze. Gnomon is 4.125 inch high, 5 inch long. Below gnomon is motto, "Horas non numero nisi serenas" (I only count sunny hours). House was built in 1805 and is now open to the public as a museum. Years before this property was opened to the public, a family member brought this dial from Crossbasket Castle in Scotland, the family seat. The lengthy inscription is probably a later addition, since it is unlikely that they would be quoting Whittier in Scotland. The gnomon angle is 39? 30', probably made for the Washington DC location. However, the dial plate has a latitude of about 48? N, certainly not Scotland. What is the true origin of this dial?
 
 
Washington District of Columbia USA Horizontal Dial Dial 203
In the Bishop's garden is a weathered 13th C. capital on which sits a 41 cm diameter horizontal brass dial. It is engraved with "Tho Heath, London" and the year 1712. On the noon line is the indication "Hammersmith", a location on the (then) outskirts of London at 51:30N 0:14W. Heath is one of the Grocers' Company mathematical instrument makers Many of Heath's dials have a coat of arms.
 
 
Washington District of Columbia USA Vertical Dial Dial 202
Vertical dial with bronze Roman numerals and trefoil pierced gnomon on square sandstone. Dial is on south facade over main entry, facing East Capitol Street. School is dated 1923 and architect Snowden Ashford. Elevation above entrance is approximately 30 ft. making dial hard to read. Large projecting towers place dial in shadow in early morning and late afternoon. Similar to McKinley High School dial (#207).
 
 
Pueblo Colorado USA Sun Alignment Dial 200
Stonehenge type dial designed by Judy Guttormsen and built in 1984 . Stonehenge itself an amphitheater. If you stand on a brass marker in the center of the stage, on the solstices and equinoxes, you can observe the rising and setting of the sun aligned with metal posts viewed through slits in the wall. At the south edge of the site is a 6 foot horizontal dial laid out in the concrete floor. There are two rings of numbers, one for standard time, one for daylight time. Not corrected for longitude, but the location is very close to the center of the time zone. The gnomon is cement and is unusually thick (approximately 40 cm), making it very sturdy, presumably to prevent vandalism. The surface of the gnomon is very rough, having embedded pebbles, making it an uncomfortable place to sit or climb. The metal inscription plate on the gnomon has faded too badly to read. The site also has a North Star finder made of wrought iron and has a small bench for children to use.

River Falls Wisconsin USA Vertical Dial Dial 185
The inspiration for this sundial, at one time the largest vertical dial in the world, came from Dr. Swensen visiting Heidelberg castle that had a large vertical dial on the wall of the castle. Construction of the Univ. of Wisconsin dial began in 1994 on the south wall of the Kleinpell Fine Arts Building. The result is a 30 x 56 foot vertical dial of anodized aluminum with analemmic hour markers, and day lines to mark winter and summer solstice, Candelmas (1/31), Martinmas (11/10), Beltane (5/8) and Lammas (8/4), vernal and autumnal equinoxes. The massive south-facing vertical dial takes up the entire wall of the three-story fine arts building.
