Michigan

	Ann Arbor	Michigan	USA	Noon Mark or Meridian Dial	Dial 1096
	Dial is a calendar dial that marks noon on the solstices and equinoxes by projecting a circle of sunlight onto one of three horizontal discs on the meridian line dial face. To create the round sunlight spots the vertical arm has three elliptical holes to match the solar angles for the two solstices and the equinox. The disk closest to the gnomon (with highest solar angle) is for the summer solstice. Middle disk is for the equinoxes, and the farthest disk (with lowest solar angle) is for the winter solstice. Notice in the photo that the summer hole in the vertical arm is considerably stretched to account for the high angle of the sun.
	Ann Arbor	Michigan	USA	Vertical Dial	Dial 199
	A stone and bronze vertical dial approximately 10x6 feet just below the roof of the Mack School. Dial face includes Roman numerals showing Eastern Standard Time and a polar gnomon. Inscription appears below gnomon.

	Ann Arbor	Michigan	USA	Horizontal Dial	Dial 1084
	This is a large monumental scale horizontal sundial. The gnomon, approximately 15-ft (4.5m) high has a brass patina and made using polygonal segments assembled almost in jigsaw puzzle style to form a large triangle. The gnomon sits at the north end of a large 30-ft (9.1m) brick plaza, wasting the area of the plaza except for a large imbedded brass plaque. Hours are simply marked by light colored granite with a pointed exterior aimed toward the edge of the plaza. Harder to see are half-hour light colored small granite triangles.
	Ann Arbor	Michigan	USA	Horizontal Dial	Dial 616
	A 6 foot (1.8m) square weathering steel horizontal dial with a 3 foot (1m) high and 6 inch (15cm) wide steel gnomon in the shape of a simple triangle. Hour lines are welded steel strips, but without hour numerals. The dial is set on a steel wedge such that on sloping ground it brings the dial face horizontal. The noon gap is an artistically designed angular strip. The hour lines are offset from local, reflecting the 26 min advance from the central time zone meridian. Local mean noon (when the mean gnomon shadow falls in the noon gap) occurs at 12:26pm CST. A Plaque with the Equation of Time to convert shadow time into CST is being developed.
	Bloomfield Hills	Michigan	USA	Equatorial Dial	Dial 770
	An equatorial dial of cast bronze. The heavily patinated dial has Roman hour numerals IIII through VIII and a cast bronze pointer marked, "DAYLIGHT SAVING." It has an unusual crescent shaped arm with notch at the upper end. The arm is rotated until sunlight passes through a hole in the upper arm and strikes an analemma with monthly dates on the lower inner curve of the crescent. Time is then read on a circular dial from an "hour hand" pointer extending from the base of the crescent. The dial sits atop a marble pedestal engraved: "The A.N. Goddard Sundial"

	East Lansing	Michigan	USA	Analemmatic Dial	Dial 384
	This garden analemmatic dial uses plants to mark time with plants selected to demonstrate bio-rhythms by their daily opening and closing at different times. Four-o'clocks are planted at the 4 block. Magic evening primroses 'Tina James' encircle the area. Flowers open in 15 seconds to the sunlight, quite a spectacular sight! Also planted here are: Evening Primroses, Portulaca 'Sundial', Coreopsis 'Sunray', Morning Glory, Thyme, Four-O'clock, and Moonvine. Children cast their shadow to tell the time. Step between the blocks of the current month, raise your right hand, and your shadow tells the time. The analemmatic dial is set up for daylight saving time.
	Frankenmuth	Michigan	USA	Vertical Dial	Dial 897
	The dial is elegantly painted on the south wall declining 30 deg west. Dial shows daylight savings time using dark red Roman numerals on a golden ribbon banner.

	Frankenmuth	Michigan	USA	Armillary Sphere	Dial 896
	This is a mass produced armillary dial held at the latitude of Frankenmuth by the statute of a boy with raised arm. All this sits on a pedestal with a Greek motif. The meridian circle made of iron is about 2 feet in diameter. The equatorial band is about 3 inches wide with some corrosion present. Inside the equatorial there appears to be an aluminum interior band of Arabic numbers riveted to the equatorial. Hours and half hours are marked by dot bumps in the aluminum. There is an iron latitude ring for decoration. The bronze gnomon extends the meridian circle with both an arrow point and feathered tail.
	Frankenmuth	Michigan	USA	Equatorial Dial	Dial 194
	This monument sundial is an Erickson equatorial polar dial 6 feet in diameter made of light granite with a 3 inch steel rod as gnomon. Time is graduated by hour, half-hour, quarter hours and 5 minute marks over 24 hours. Noon is at the bottom, matching the 105 degree meridian. Designed to be read from the upper surface in Spring/Summer, from the under side in Fall/Winter. Unlike other Erickson dials, the Equation of Time plaque is presented in a circular arc on the ground.
	Grand Haven	Michigan	USA	Equatorial Dial	Dial 601

	A cast iron statue of a small boy painted in gold and kneeling. With arms upright, he holds a plate on top of his head that held the original sundial face, surrounded by an inscription and ornamentation. The statue is bolted to a concrete pedestal. With the original sundial gnomon removed, a new oversized horizontal dial has been carelessly bolted onto the top plate. The gnomon and dial face imply it is a British reproduction, totally unsuited for the Michigan location. The dial face is ornate, with a compass rose in the center, surrounded by a chapter ring divided in 15 minute intervals. A second, outer chapter ring divides time into 5 minute intervals. Time is indicated with Roman numeral hour marks. Dial in good alignment, but illuminated by the sun only during early morning.

	Lansing	Michigan	USA	Vertical Dial	Dial 923
	This is a vertical, east-declining sundial, 22 ft 6 in by 15 ft 10 in. The dial is constructed of 6061 aluminum alloy pieces electrostatically painted and bolted together,then mounted on a concrete block wall. The position of the gnomon, hour, solstice, and equinoctial lines are corrected for longitude to show time zone solar time. Stenciled hour line numbers are changed to display DST or EST at appropriate times of the year. Visitors can determine the correct time by referring to an Equation of Time display. During the year, the triangular gnomon tip casts its shadow on the declination lines of summer and winter solstices and equinoxes. This is the largest known vertical sundial in Michigan, and one of the largest in the United States.
	Mackinac	Michigan	USA	Horizontal Dial	Dial 183
	ca 16 in. square brass horizontal dial. Hours from 5am to 7pm in Roman numerals. Arrows radiate from the foot of the gnomon to each hour and three stars are located at the south end of the gnomon.

The dial now sits in a small brick plaza.

	Ypsilanti	Michigan	USA	Horizontal Dial	Dial 1086
	This is the original horizontal dial and gnomon of 1909, cast in iron as a gift from the Class of 1908 (then known as the Michigan State Normal School ). This sundial was originally located on the west side of the sidewalk coming from the main south entrance of Serzer Observatory on the Eastern Michigan University campus, now the location of the EMU "Sesquicentennial Sundial". [See NASS Dial #346] This original dial is about 12 inches (30cm) with Roman hour marks from 6am to 6pm on the edge of the dial. Hour lines extend from the edge to about half way to the gnomon foot.
	Ypsilanti	Michigan	USA	Horizontal Dial	Dial 346
	The original horizontal dial and gnomon of 1909 was cast in iron as a gift from the Class of 1908 (then known as the Michigan State Normal School ). This dial is now in the EMU archives.[See NASS Dial #1086] The current sundial was placed in the same spot in front of Serzer Observatory in the 1960's, but went missing after a broken gnomon was sent for repair, and was lost for 30 years. In 1999, during the sesquicentennial celebration of the university, EMU had the sundial restored by Arnets Becker Burrell Monuments of Ann Arbor. They also had the sesquicentennial logo added to the pedestal. The restoration was funded by the Serzer family. The elegant weathered brass and copper dial is now known as the "Sesquicentennial Sundial". Surrounding the dial are lines in the granite plinth to the cities of Montreal, Detroit, Boston, New York, Whittington DC, Toledo, New Orleans, St. Louis, Chicago, Kalamazoo, Grand Rapids, Lansing, and MT Pleasant. The original Class of 1908 4-ft (1.2m) granite pedestal still holds the sundial, including its mark of "150 years".
