Bowie Maryland USA Vertical Dial Dial 372
A small vertical stone dial with a weathered wood gnomon is mounted with iron brackets to the wall of Sacred Heart Chapel. The dial is about 26 inches wide by 16 inches high. The inscribed longitude of 00 deg 20 min East is correct for the United States Prime Meridian which goes approximately up 16th Street in Washington DC. In 1853, fire destroyed everything but the walls of the chapel; it was reconstructed in 1858. The present stone dial is reported to have been made by Francis J. Deutsch, Sr., replacing and duplicating the original. See NASS Compendium Vol. 5, No. 3, Sept., 1998. The whole dial is now covered with white paint and the gnomon which is set at 42? is placed upside down. The wall is 7? SE but the dial was designed for true south.
Denver Colorado USA Horizontal Dial Dial 371
The horizontal stone dial face is about 45 inches across, and is raised eight inches above ground level. It is inscribed with hours from IV to VIII.

Guelph Ontario Canada Horizontal Dial Dial 370
On the Sunnyside Estate front entrance is a small horizontal dial on a white pedestal surrounded by a flower garden. The original of this sundial is reputed to be the one that was mounted on the stump of the tree felled by John Galt in his ceremonial founding of Guelph on April 23rd, 1827. The original dial and pedestal were carved from Guelph limestone, and are in very poor condition. They were moved indoors during renovations in 1979. A replica now stands in the original position. See NASS Compendium Vol. 6 No. 3, Sept. 1999.
Reston Virginia USA Horizontal Dial Dial 369
A modernistic seven foot diameter flagstone horizontal dial with hour lines. The design features a gnomon of folded stainless steel plate. Gnomon is truncated too short for shadow to reach edge of dial face. See "Sightings" in NASS Compendium Vol. 6 No. 4, Dec 1999.
Denver Colorado USA Vertical Dial Dial 368
On the southwest side of the Emerson School Building (now an office building and historic landmark) is a large white stone vertical dial with a stone gnomon. The large stone dial is part of the original brick building erected in 1884. Local history holds that the original architect was somewhat staid and stuffy and only agreed to include the sundial "because of its educational value." The dial was restored when the building was refurbished. See "Sightings" in NASS Compendium Vol. 6 No. 4, Dec 1999.
Casper Wyoming USA Horizontal Dial Dial 367

Enid Oklahoma USA Equatorial Dial Dial 351
A striking stainless steel equatorial dial 6 ft tall, 4 ft wide, and 6 ft deep. The equatorial ring is more than 2 ft wide. The dial can be used as a simple equatorial dial, reading the hour from a shadow cast by the steel wire gnomon aligned to the polar axis. However a bead nodus located in the middle of the wire casts its shadow onto the equatorial ring as well. An analemma on an arched plate is set to slide along the equatorial ring in a track. By sliding the plate to a position where the nodus shadow falls on the analemma for the day of year, the dial corrects for the Eot. Markers on the analemma plate point to the correct time at the edge of the ring. The top of the ring is inscribed for Central Standard Time and the bottom is inscribed for Central Daylight Time. Overall, the sundial is accurate to about a minute any day of the year. The analemma was computed by Lt Col Bill Welker, USAF and the dial was funded by McCasland Foundation.

Baltimore Maryland USA Horizontal Dial Dial 326
Very bad small dial on a beautiful stone pedestal. The engraving on the base states that it was erected in 1908. At some point the dial face went missing. A new dial was installed sometime before 1966. It is doubtful that the existing dial is a replica of the original. The stylistic differences between the design of the pedestal and the design of the new dial which sits atop it are apparent. The gnomon is now missing from the dial.

Baltimore Maryland USA Horizontal Dial Dial 323
Nice horizontal dial sitting on a 6 x 4 foot stone pedestal. The dial itself is 5 foot in diameter with a 2.5 foot gnomon of open-work bronze. The lines, numerals and lettering of the dial face are so finely done that one cannot tell whether the dial plate was made of cast stone or was carved by an extraordinarily skilled mason. The gnomon, unfortunately, is situated incorrectly on the dial face. The point at which the stile diverges from the dial plate is about five inches south of the correct point where the hour lines converge.
Schenectady New York USA Sculpture/Artwork Dial 322
Sundial in the shape of a Crouching Indian
Rehoboth Beach Delaware USA Horizontal Dial Dial 321
A bronze horizontal dial about 18 inches in diameter. The sundial was designed by Col. W.S. Corkran in 1930 and placed in the Homestead House garden, a 3 1/2 acre site maintained by the Rehoboth Art League since 1938. Col. Corkran died in 1962. The sundial was restored in 1999, set atop a capstan from an old sailing ship. Since 1999 the salt air has continued to deteriorate the plaques and gnomon. The dial face is still quite readable, with Arabic hours from 6am to 6pm delineated in 5 minute intervals. Symbols of the zodiac decorate the dial in a circular arc.
Wilmington Delaware USA Vertical Dial Dial 320
A round limestone vertical dial about 3 feet in diameter with bronze gnomon. Hours are bronze Roman numerals. No hour lines drawn. The dial is set on the side of a beautiful stone tower. According to a plaque at the tower's base, in 1895 Theodore Leissen recommended a large pavilion and observatory be built on the city's highest hill. At the same time the Water Commission needed a water tower. The plans were merged, resulting in a combine stone water tower 115 feet tall holding half a million gallons and a roofed observatory platform. The dial is on the side of this Rockford Tower.
