| The Anthem Veterans Memorial in Anthem, AZ was dedicated on November 11, 2011 at 11am (11-11-11) to honor the service and sacrifice of the United States armed forces and to provide a place of honor and reflection for veterans, their family and friends. Veterans gather here annually on November 11th to watch a solar alignment at 11:11am when the sun precisely illuminates a 3-foot medallion of The Great Seal of the United States. |

Analemmatic Dial |
Dial 819 |
| This analemmatic dial is approximately 20 feet wide by 12 feet long, constructed of reinforced, high strength cast-in-place concrete. Showing both Standard and Daylight Savings Time, the dial uses a dual ring of twenty-eight circular hour markers. Each hour marker is a 12 inch diameter precast paver flush with the surrounding landscaping with an aluminum Arabic hour numeral on top. |

| A large 1m (3-foot) bronze sundial is set on a low granite dais at the center of a white granite ellipse. Surrounding the sundial are three white granite benches, the center declaring this as a memorial to Mayor James Baxter. The hour ring gives the hours from V in the morning to VII in the evening The ring is further divided into 15 minute increments. The dial has a large 24-point star and on the south end of the dial face the words "Baxter Boulevard". The artful gnomon is about 1-inch thick. Unfortunately the monument setting is heavily wooded and little sunlight reaches this fine dial. |

Equatorial Dial |
Dial 817 |
| This 9-foot stainless steel equatorial is the centerpiece of "Galileo's Garden". The sundial was built and dedicated in memory of Kathleen Fischer, a sixth-grade science teacher who inspired many students to pursue science. The sundial is an open armillary, with an adjustable hour band so that both local solar time and civil time can be read. At the tip of the gnomon is a bronze and brass true-size rendering of Galileo’s first telescope, honoring the 400 years since Galileo explored the heavens. The North American Sundial Society was privileged to donate to this effort. |

Dial 816 |
| This monumental stainless steel sundial was built as part of the Grande Prairie Millennium Project. The beautiful gnomon is 12m (40-feet) tall and symbolizes the passage of the year 2000 into the 21st century. Behind the visible stainless steel cover of the sundial's gnomon is a one by two foot steel beam. Engineers adopted computer programming techniques to construct and align the 30 centimetre thick gnomon of the Centre 2000 sundial. Specific factors such as the city’s elevation, its latitude and correction longitude mark time with the region’s Mountain Standard and Daylight Savings Time. |

Obelisk or Vertical Gnomon |
Dial 814 |
| Amid the many coral blocks (oolitic limestone rock) carved by eccentric Edward Leedskalnin (1887-1951) is a huge monolithic sundial. The gnomon is a horizontal L-shaped piece of iron fastened to the north corner of a limestone block about 8 feet high, weighing about 15 short-tons. Below the gnomon, carved into a second block of limestone is a portion of a hemisphere, smoothly filled in with concrete. Drawn on the hemisphere are analemma shaped hour and half-hour lines from 9am to 4pm. You can read the time with an accuracy of about two-minutes. |

| In 2013 the city of Coeur d'Alene began a $20M renovation of downtown McEuen Park, a 22-acre expanse, to include a large sundial. But shortly after the renovation started, the city commissioners were told the $51,000 that was to be spent on the sundial was instead to be used to install heavier electrical infrastructure for support of major park events. Fortunately by the end of 2013, the City Staff announced that the sundial was added back to the park's plan, made possible by a $50,000 donation from Parkwood Business Properties. |

Sun Alignment |
Dial 810 |
| This solar alignment sculpture called the "Sun Triangle" is made of polished 1/8 inch stainless steel. Its leaning, 10 foot tall pedestal gives the mounted triangle a futuristic look of monumental size, where the tip of the triangle towers 34 feet above ground level. The selected triangle angles are described by the dial plaque, making solar alignments at noon on the equinoxes and summer/winter solstices. There are no line markings or hour indicators on the ground. However, the pedestal is bolted to a buried concrete block weighing approximately 16 tons. |

The gnomon is triangular in cross section with a single thin edge casting the shadow. The dial hour numbers are set for daylight, since all of the winery's 100,000 annual visitors are seasonal, coming when Pacific Daylight Time is in place. |

Analemmatic Dial |
Dial 804 |
| Work to design and make the Analemmatic Sundial was done by students of the sixth grade science class and teacher Eric Newell in 2005. The central walkway uses stepping stones sandblasted with the name of the months. John Westenskow's ceramics classes at Mount Logan Middle School made the time stones. Students surveyed and plotted the location of the stones and provided the physical labor to dig holes and pour cement. |

Cylindrical Dial |
Dial 803 |
| This is an adaptation of the dual cylindrical sundial design by Hoffmann Albin of Butgenback, Belgium that provides for two separate dials to be displayed. In this variation, the two dials are separately displayed after being rotated and locked into viewing position every six months on the solstices. Except for two bronze sleeve bearings, all parts are 304 stainless steel that has been glass bead blasted to reduce reflection, machined, welded or laser cut. The analemmal hour lines, equinox and month lines are laser etched into the stainless steel dial plates. The dials and their supporting cradles are 12 gauge with 12" diameters. The post is 1.75" in diameter. |

Horizontal Dial |
Dial 783 |
| A 28 x 20 x 2 inch sandstone horizontal dial with a 1/2-inch thick, hand-tooled copper gnomon. Dial face has Arabic numerals and hour lines corrected for local longitude. Dial was hand carved with carbide chisels and maul but using techniques and natural stone used to create ancient Native American petroglyphs found in the southwest USA. Dial is mounted 2 inches above a sandstone base weighing 400 pounds by brass leveling pins; this mounting makes the dial appear to "float" above the stone base.
A "Desert Varnish" finish has been applied to the dial face using a natural process that mimics what naturally happens to exposed sandstone over several thousands of years. The natural color of the stone is exposed by the carving process to create a color contrast as might be seen in a Native American petroglyph.
Dial is located in the front yard of a private residence. Viewing can be arranged by contacting the owner by email at theoperativemason@gmail.com |

| A school yard 6 by 4 meter analemmatic dial of pigmented concrete. The Sunclocks registered design has two hour ellipses, the outer one for standard time, the inner one for daylight saving time. The zodiac table is larger for the fall and winter periods so the design is really two sundials in one. Longitude correction is included. The plaque provides instructions in French and English and notes the dial marks the 50th anniversary of Ecole Banff Trail.
The plaque instruction to stand on the current month is misleading; the user should straddle the dial centerline to avoid an offset error. |

Dial 779 |
| A 12 foot high noon mark dial consisting of two closely spaced triangular vertical plates, a protruding needle and pairs of summer and winter solstice "wings" that together project a shadow onto the surrounding concrete deck within a 40 foot diameter reflecting pool.
When the sun totally illuminates the narrow space between the vertical plates, it is local noon and the shadow cast by the protruding needle points true north. On the summer solstice, the shadow cast by the smaller, upper solstice wings will be at its narrowest width. On the winter solstice, the shadow cast by the lower solstice wings will be at its narrowest width. |
