The dial is inclined to accommodate the latitude of Bethesda, MD. The dial sets on a simple cylindrical pillar.
 
 
Bethesda Maryland USA Horizontal Dial 461
A simple but elegant horizontal bronze dial approximately 18 inches in diameter. Design is a standard design used at U.S. Naval Hospitals. Has plain raised hour lines and half-hour lines with Arabic numerals. The dial tells time from 6 AM to 6 PM. The accompanying plaque reads, "Cast especially for the Naval Hospital at Brooklyn, New York. This bronze sundial stood on the grounds from 1924 until the hospital was disestablished in June 1948?"

Newark Ohio USA Analemmatic Dial 460
An analemmatic dial with stone markers for the hours
 
 
Tenango de Doria Hidalgo Mexico Vertical Reclining Dial 459
A very striking vertical reclining dial 85 x 115 cm created from hand painted tiles, each individually fired in a kiln and assembled at Tenango de Doria by David Canyedo. In addition to hour lines, the dial includes declination lines for the solstices and equinox. The dial includes constellation maps of both the northern and southern hemispheres, a celestial sphere, and rose of winds (compass). The artistry also includes NAHUI OLLIN (the fifth sun which is the era we are living in according to the Aztecs). The dial has an equation of time that allows conversion from local solar time to standard time. The dial was designed to arouse interest of high school students in astronomy.
 
 
Bullhead City Arizona USA Horizontal Monofilar Dial 458
This horizontal dial is an engraved flagstone approximately 42 inches in diameter designed by John Carmichael. The monofilar gnomon is a stranded brass cable that extends upward to a height of 18 inches and is held taught by a rock counterweight. Hour lines and direction of sunrise and sunset for the equinoxes and solstices are given. Also has noon Mark, The Equation of time, and a 32-point Compass Rosette
 
 
Casa Grande Arizona USA Horizontal Monofilar Dial 457
This horizontal dial is an engraved flagstone approximately 40 inches in diameter designed by John Carmichael. The monofilar gnomon is a stranded brass cable that extends upward to a height of 15 inches and is held taught by a rock counterweight. The engraved stone shows time marks to 5 minutes, corrected for longitude. Time and direction of sunrise and sunset for the equinoxes and solstices are also given.
 
 
Tucson Arizona USA Vertical Dial 456
This is a 10 x 10 foot south vertical wall dial with hour lines painted on the wall that are corrected for longitude. A unique feature of this dial is the time scale can be rotated forward or back slightly to compensate for the Equation of Time. However, because only the hours are marked, precise minute reading is difficult. Welded steel was used to make the time marker ring and gnomon.
 
 
Halifax Nova Scotia Canada Horizontal Dial 455
This bronze horizontal dial is approximately 25 cm across on a one-meter high pedestal. Both the dial and dedication plate have a blue-green patina. The gnomon is slightly bent and appears to have been re-attached to the dial. The orientation remains true. Roman numerals mark the hours from 5 am to 7 pm. Hour lines plus half-hour marks. The concrete base is badly cracked and small pieces have fallen away. The dial is well-situated in an open area, but a nearby tree might shade the dial near midday during fall, winter, and spring.
 
 
Juneau Alaska USA Analemmatic Dial 454
Painted on a downtown sidewalk is an analemmatic sundial for public use. The 25 x 20 foot sundial was organized as a community project. Eden Orelove, niece of designer Michael Orelove said, "We wanted to get as many school classes and local volunteer organizations involved as possible." Groups were invited to join the project by painting the hourly numbers. Two concentric ring of numbers are used to indicate both standard and daylight saving time, which extends from 4 am to 10 pm.
 
 
Mexico City Distrito Federal Mexico Horizontal Dial 453
A triangular based horizontal dial with a triangular moat. The outer triangular sides are approximately 12 feet (4 meters). The dial and moat are built of concrete, with an aluminum or sheet metal gnomon about 150 cm. On the dial are metal pyramids to indicate hours. The sundial was donated by the Tecnologico de Monterrey University.
 
 
Las Cruces New Mexico USA Equatorial Dial 452
A large equatorial dial with steel gnomon. The massive dial is set simply on a set of tiered platforms. The inner tiers are rotated from the outer to align to the cardinal points. Elsie Raye Rigney Carr and Dr. Jesse Lawrence Carr gave the dial to the university in 1975 in memory of Raye Hines Rigney, Class of 1911.
 
 
Elizabethtown Pennsylvania USA Vertical Dial 451
A 4x4 foot marble vertical dial declining 25° east of south with a copper gnomon, located above the center entrance of the Grand Lodge Hall and overlooking the formal garden of the Masonic Village of Elizabethtown. The dial face includes hour lines with half hour and ten minute marks and Roman numerals. An inscription, "ANNO DOMINI MCMXII" is located above the gnomon. The dial declines 25° east of south.
 
 
Kingston Ontario Canada Vertical Pillar Dial Dial 450
A square pillar of limestone rocks 4 foot on a side and 15 feet high with a small bowl and sphere on top hold two vertical dials each 2x2 feet. The pillar faces are oriented SE and SW allowing for two declining dials. The dials are of solid brass and have hour lines with Arabic numbers in a modern design belying by the stonework of the pillars. Unfortunately the 14-inch gnomons are bent
 
 
Ottawa Ontario Canada Hemisphere Dial 449
This hemispherium dial is a dramatic modern sculpture. The 32 inch quarter hemisphere is carved into the edge of a 40 inch cube of dark granite tilted to conform to its latitude of 45.5° , and set upon a rough concrete pedestal of slightly smaller dimension. The gnomon is a
 
 
Calgary Alberta Canada Equatorial Dial 448
A steel and brass equatorial dial 49 inches in diameter. The dial simulates an armillary sphere with two crossed semi-circles in a modernistic sculpture. There is a slot in the gnomon that projects a sun line and corrects for the equation of time; the gnomon is turned over at the solstice. Fine adjustments are required near the solstice to show correct clock time (MST). Dial built as a Canadian Centennial Project. Now relocated to a mid-level landing on the entrance stairs but not correctly aligned, producing a 48 minute error.
 
 
Bloomington Minnesota USA Polar Equatorial Dial 447
An Erickson Monument polar equatorial dial of light granite, approximately 5 feet in diameter and 6 inches thick. The gnomon shaft is steel, 3 inches in diameter, extending from the ground through the dial plate and outward another 18 inches. The base is a simple tier of raised concrete. 24 hours of radiating lines are inscribed on each side of the dial (summer and winter), ending with the hour in Arabic numbers. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 5 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [The description to obtain watch time attributes Bloomington's longitude as 93:18 East instead of West. Further, it tells the user to subtract one hour for daylight savings time.] Nearly identical to the Port Arthur Dial, Texas, but without city names located in various time zones. Compare this dial with other Erickson dials
 
 
Port Arthur Texas USA Polar Equatorial Dial 446
A large Erickson Monument polar equatorial dial of light colored granite, approximately 6 feet in diameter and 6 inches thick. The gnomon shaft is steel, extending from the ground through the dial plate and outward another two feet. The base is a simple tier of raised concrete. 24 hours are inscribed on each side of the dial (summer and winter) as radiating lines with Arabic numbers at the end. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 6 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [An interesting note about the engraving for the Apr-Sep graph: The line originally said "For daylight savings time, subtract one hour", the word "subtract" was filled in and "you add" was inscribed over it.] In the top quadrant of the dial (both obverse and reverse) where the sun's shadow will never cast, are the names of cities in 16 different Time Zones. A beautiful and well-crafted sundial, it makes a fitting Seaman's Memorial. Compare this dial with other Erickson dials
 
 
Lewisburg Pennsylvania USA Equatorial Dial 445
A large, ornate equatorial dial of brass sits outside the physics department building. The dial is approximately 8 feet across. Two pillars with brass balls support the dial plate. Two more pillars with ball support the gnomon wire. To add a flourish, the north most pillar and ball have a spread eagle holding the gnomon wire in its mouth. Unfortunately this beautiful dial is tarnished by age, with the analemmas for each hour barely visible on the dial plate. The gnomon wire, broken sometime in the past, is jury-rigged and tied together in the middle, resulting in a unkempt look to such a fine dial. A dark, round stone base, perhaps made of slate, approximately 8 foot in diameter supports the dial and pillars. The stone sits upon a 10 x 10 foot concrete pad.
 
 
Wilmot Ohio USA Horizontal Dial 444
The Wilderness Center Sundial is large horizontal dial with a 6-foot steel gnomon approximately 27 inches thick. The base is done in slate with copper numbers.
 
 
Newburyport Massachusetts USA Armillary Dial 443
This 4-foot diameter armillary sphere is made of galvanized, painted and gold leafed steel. The dial is had forged and welded by Cassidy Brothers Forge. It was "Colorgalvanized" by Duncan Industries and gold leafed. It was made to specifications from Albert Waugh's book on sundials, including latitude and longitude corrections. The sundial is mounted on a cast stone pedestal and stands about 8 foot high.
