Bloomfield New Jersey USA Armillary Dial 109
An armillary sphere 5 feet in diameter, with a bronze 8 inch equatorial band holding hour marks on the inside and decorated with animals of the zodiac on the outside. A simple rod serves as the gnomon. The armillary is supported by 8 cast bronze turtles on top of a four foot cylindrical pedestal. The turtles point to the cardinal and intermediary points of the compass. This very handsome dial was made by Kenneth Lynch.
Bloomfield Hills Michigan USA Equatorial 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 through the notch strikes an analemma 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."
Bloomfield Hills Michigan USA Horizontal Dial 292
Bronze horizontal dial. "Sundial Family"
Bloomfield Hills Michigan USA Horizontal Dial 837
In the Cranbrook Gardens, where works of art topiary and American crafts are displayed, one can find a brass horizontal dial transformed into a beautiful sculpture of a swan with the tail serving as the style, and the hour lines are the feathers of the wings. A small circle with Arabic numbers delineates the hours.
Bloomington Indiana USA Horizontal Dial 38
A small horizontal dial, about 18 inches in diameter. The dial plate is tilted 2 deg to the horizon to allow water run-off. However, more unusual is the base that contains a hand crank connected to a scalloped drum that tilts the entire dial to adjust for the Equation of Time. The drum is rotated to the current date and the drum edge pushes a cam that tilts the plane of the horizontal face so that standard time is indicated to within half a minute. The dial is actually mounted on an equatorial axis. Since 1979 the dial has gone into a state of disrepair and is overgrown by bushes. In July 2011 it is reported that the adjusting knob no longer works to tilt the dial.
Bloomington Indiana USA Horizontal Dial 336
A 24 inch octagonal horizontal dial probably made of marble. The dial is plain, with Roman numerals at the end of hour lines. The gnomon is a simple open triangle of well aged brass. The base is an octagonal pillar surrounded by flowers. The dial was struck by a falling tree in spring 2011. The gnomon style is broken and bent and the support has several large cracks. The falling tree also damaged the surrounding fence.
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
Bloomington Indiana USA Vertical Dial 728
An approximately 4 foot square, limestone south-facing vertical dial with a bronze gnomon. Dial face has hour lines and half-hour marks with Arabic numerals. Tall trees shade the dial most of the day.
Boise Idaho USA Equatorial Dial 344
Equatorial dial 5 ft high, 6 ft. wide and 4 ft. deep. The dial was designed by Pete Swanstrom, built and donated by JST Custom Fabrication Inc. of Boise. The gnomon is of unusual design with a central pivoting elliptical plate and analemmatic cut out. The analemma is marked with 365 individual date marks. Shadow falls on equatorial ring with hours marked from 7am to 7pm and inscribed with lines for every minute (spaced 1/7 inch apart). Indicates time to less than 15 seconds, making it among the most accurate sundials in the world. Indicates true time to the minute, date to the day, and adjusts for Daylight saving time. The Latin inscription should read "Tempus Captum" rather than "Tempus Captus".
Boston Massachusetts USA Horizontal Dial 280
A bronze horizontal dial with bronze figures of a bird with baby birds in nest and worm as gnomon.

Boulder Colorado USA Equatorial Dial 172
A large polar equatorial dial by Erickson Monuments, known as the "Tippit Sundial" given by John Tippit in memory of his son. The dial is of dark red granite, 6 feet in diameter and 6.375 inches thick. The gnomon shaft is steel, extending from the ground through the dial plate and outward another two feet. 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. Designed to be read from the upper surface in Spring/Summer, from the under side in Fall/Winter. The hours on the under side of the dial were originally engraved backwards. Two plaques provide the Equation of Time to convert solar time to watch time. The dial rests on a cement work 7 feet high.
Boulder City Nevada USA Vertical Dial 691
A 2x3 foot vertical stained glass dial declining 44.3° west of south permanently located in the living room window of a private residence. Dial has a uniquely attached point-in-space nodus on a perpendicular gnomon secured with a magnet to an embedded steel disk in the glass dial face, preventing damage should the gnomon be struck. Dial face includes hour numerals, half-hour lines, solstice and equinox lines and a solar noon mark. Dial face consists of 210 pieces of glass, 40 feet of lead and zinc came and 20 engraved and hand painted pieces of glass. The frog-shaped perpendicular gnomon can be replaced with a ball-shaped gnomon.
Bowie Maryland USA Vertical 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.
Bowie Maryland USA Vertical Dial 712
The Bowie Portal Dial is a 48x66 inch vertical dial of frosted glass atop two 15 foot tall steel beams. The dial face has bronze filigreed hour lines, Roman hour numerals and a supported bronze gnomon. The translucent glass allows the dial time to be read from both sides. At ground level the two steel beams are surrounded by steel benches covered in granite and form a portal with the silhouette of playing children cut of brass sheet riveted to the stainless steel base. The 11 foot wide base depicts running horses cut in brass and sits atop a 16 foot diameter compass rose. The base includes a plaque with the EOT.
