You may also type into the NASS search field at upper right any search word such as "equatorial" to get a list of all articles mentioning equatorial dials and a list of all equatorial sundials in the registry. (Try other dial types: "vertical", "horizontal", etc).

	Silver Bay	Minnesota	USA	Horizontal Dial	Dial 227
	A horizontal dial on the ground, with an hour circle about 12 feet. The gnomon is of steel, about 4 foot high. The gnomon is oriented to magnetic north. It is not an accurate device. Three boulders surround the dial and cut off the shadow much of the time. Gravel hour circle has rocks to mark the hours, but the rocks can be moved and are strewn all about. More suggestive of a dial than a real dial.
	Macon	Georgia	USA	Horizontal Dial	Dial 226
	A horizontal dial 16 inches in diameter located beside the observatory, just outside the museum. Includes hour markings for EST and DST and an EOT graph. Hour lines corrected for longitude. Mounted on a 24 inch high pedestal low enough for children to enjoy.
	Steamboat Springs	Colorado	USA	Equatorial Dial	Dial 225
	This equatorial sundial is a memorial to Barbara Perry Cosel and sits in front of the"Bud" Werner library. A large 6 ft. thin iron equatorial, it is constructed of two 270 degree arcs that intersect at right angles. Time marks are simple detente marks on the equatorial arc. The gnomon is a traditional arrow. At the base of the dial is a plaque containing a graph of the Equation of Time to determine Mountain Standard Time.
	St. Petersburg	Florida	USA	Equatorial Dial	Dial 224
	An equatorial dial built by Erickson Monument Co in 1974 for the War Veterans Memorial Park. Dial is 6 feet in diameter made from granite. The gnomon rod of about 3 inches diameter is stainless steel. Hour, half hours, quarter hours and five minute marks show the time. For symmetry, the face has hours marked for the entire 24 hours, though in Florida the excursion of time from 6am to 6pm is relatively small. The hour lines are rotated for the site longitude.
	Chicago	Illinois	USA	Equatorial Dial	Dial 223
	Henry Moore Sundial Sculpture: 13 foot bronze equatorial dial built in 1980. Two bronze semicircles, one set inside and at right angles to the other, form the main elements. A slim rod runs from one end of the outer semicircle to the other end and its shadow on the inner semicircle below marks the time of day. EOT correction is provided.
	Colorado Springs	Colorado	USA	Analemmatic Dial	Dial 222
	Analemmatic dial in granite and bronze. 9ft x 12ft. Mottled granite block surface with number border of smooth granite blocks. Hour numbers are engraved in granite. Zodiac marker is brass, embedded in the granite face. As with most analemmatics, the dial is not corrected for longitude. Fortunately, the location is very close to the center of the time zone at 105 deg W. User stands on a central analemma at correct date and acts as the gnomon to cast a shadow that points to local solar time. The aspect ratio is not correct for the latitude and the positions of the solstice markers are slightly off.
	Lake Buena Vista	Florida	USA	Gnomonic or Projection Dial	Dial 221
	Conical dial 120 ft. high, 122 ft. diameter at base and has an 85 ft circular opening to the sky. In the middle of the opening is a spherical nodus that casts its shadow into the concrete structure. According to the Guinness Book of Records in 1995, this is the world's largest sundial. Designed by Isozaki and calculated by Ross McCluney, the sundial is a large truncated, slanted cone, with hour markings on the inside. McCluney was NASS's first president.
	Indianapolis	Indiana	USA	Equatorial Dial	Dial 220
	A five foot diameter donut-shaped full circle equatorial pierced by equally massive Indiana Limestone shaft as gnomon. Hour numerals are Arabic. Subdivided into 15 minute increments. Equation of Time is given in the plaque at base
	Oberlin	Ohio	USA	Vertical Dial	Dial 219
	Once, high on the physics building south wall was a student made vertical dial. The 5'x8.5' resin coated particle board made by Mark Kearns in 1979 had curved hour lines to account for the equation of time, declination of wall, and offset from standard meridian. This dial has not been on display for some time. Perhaps some student would create a new dial. The brick wall is an excellent location.
	Washington	District of Columbia	USA	Horizontal Dial	Dial 218
	Horizontal dial 12 in. square designed and built by David Shayt and David Todd of the Smithsonian Institution. Roman numerals, 5AM-7PM. Subdivided into 15 minute increments. Also has compass rose. Dial sits atop a rectangular granite pedestal.
	La Crosse	Wisconsin	USA	Equatorial Dial	Dial 217
	A 40 inch diameter armillary on a 2 foot tall cement cubic base. The original analemma-shaped gnomon was missing and replaced with a section of loose ordinary electric wire. Includes a longitude-correction plaque showing the corrections throughout 15 degrees longitude. Dial sits atop a 26 inch high, 26 inch square pedestal. Robert Allen states that this dial is a scaled down version of the one at the San Diego Zoological Garden, and that there is a similar one at Williams College in Williamstown MA.
	La Porte	Texas	USA	Armillary Sphere	Dial 216
	Approximately 6 foot diameter bronze armillary dial with equatorial, meridian and equinoctial colure rings and with Arctic and Antarctic circle rings. Hour lines have 5 minute marks and Roman numerals. Equatorial ring has Zodiacal signs. Base shows the Great Seal of Texas and includes a bronze eternal flame. Names of fallen heroes are inscribed on the base and paths to and from the dial lead to location of Sam Houston's troops prior to the battle of San Jacinto. The San Jacinto Monument is seen in the distance.
	New York	New York	USA	Cylindrical Dial	Dial 215
	A half-cylinder equatorial dial whose body structure is exactly the same as the one (#28) at Trinity College, Hartford, CT, only the pedestal here is lower. Named ?The Camp Columbia Sundial?, a gift of Camp Columbia to memorialize Dean Hennessy (1917-1991).
	El Cajon	California	USA	Armillary Sphere	Dial 214
	Armillary dial about 3 ft. diameter designed by Don LeGrande. As of Christmas 1992, a stunning armillary sphere-type of sundial ... The framework of the dial is constructed of burnished stainless steel. ... The rod-like gnomon was destroyed by vandals many years ago, but the rest is in good shape.
	San Diego	California	USA	Horizontal Dial	Dial 213
	This is not the Koester dial at SDSU, but a far more interesting horizontal dial originally dedicated to the San Diego Normal School for elementary teaching by the class of June, 1911. The 18-inch octagonal bronze dial was originally designed by San Diego Clock maker Joseph Jessop and mounted on a miniature Doric column. The dial was placed within the circular lawn directly in front of the school's main entrance at the intersection of Park and El Cajon Boulevards.
	Anacortes	Washington	USA	Vertical Dial	Dial 212
	4'x8' Marine Plywood & Aluminum Gnomon and struts made of copper plumbing pipe. Refurbished by Threet in 1992.
	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).
