Pasadena California USA Analemmatic Dial 643
A 14x8 foot analemmatic dial with an 8x2 foot gnomon-positioning calendar plinth. The dial is installed in the pebble and concrete patio of the Winnett Student Center. The hour markers and calendar line plinth are made of Granodiorite of Knowles, a muscovite-bearing biotite granodiorite rock quarried from Knowles Quarry at Raymond, California. A nearby wall plaque provides longitude and EOT correction. The dial is a gift from the Caltech Alumni Association as a sculpture, a public artwork and a scientific instrument. This dial is located on the private university campus but the public may walk on the campus grounds to view the dial.
Pearl City, Oahu Hawaii USA Horizontal Dial 535
A 28 foot stone horizontal dial with 8 foot high black wood and fiberglass gnomon located in a children's Sundial Garden. Hour markers are Roman numerals cast into concrete blocks. Dial is screened by koa and lonomea trees.
Pekin Illinois USA Horizontal Dial 233
A unique horizontal dial using both a sloping 15 foot aluminum gnomon and much taller 45 foot vertical pole. The ground level dial face consists of seven analemmas drawn in the grass field that surrounds the dial center. The analemmas are drawn for the hours 8-AM to 3-PM 3, corresponding to the tip of the sloping aluminum gnomon. However, the noon analemma is larger and corresponds to the shadow of a disk atop the vertical pole. The board of directors for the Pekin Park District offered a large place in the Mineral Springs Park Sunken Garden for Henry Cakora's desire to build a sundial. Henry designed and cast the dial, and the dial was built with assistance from local contractors and individual volunteers.
Pennington New Jersey USA Cylindrical 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.
Penticton British Columbia Canada Analemmatic Dial 240
This analemmatic dial, called the Skaha Solar Timepiece is on a lakefront beach, spanning an area of 65 x 35 feet. At the center is a large 15 foot raised wooden platform supporting a flat steel analemma with months/dates pierced through. Observer stands on current date to be the gnomon. The hour markers are short concrete posts. These posts, which form an ellipse around the platform, were originally wood when the dial was first designed by Gwen Boyle a sculptor from Vancouver. After 14 years of weathering, the rotting wood was replaced by concrete during renovations in 1998.
Peoria Illinois USA Horizontal Dial 607
An 18 inch octagonal horizontal dial of cast bronze. The dial face includes hour lines with ten minute marks and Roman numerals. The dial is on an octagonal polished granite pedestal. The bronze gnomon is correctly set at 40? but appears to be more modern than the cast dial face. This is one of two "sister" dials ordered cast by Grant Hood; the second dial was placed at Bradley School of Horology but later disposed and now in private ownership in Lynchburg, Virginia.
Perryville Missouri USA Horizontal Dial 882
The square 14.5-inch dial is made of while milk stone with graphics highlighted using lithochrome paint. The gnomon is made of stainless steel 303-alloy and has the letter P held between the base and style. The dial sits upon a square frustrum pedestal 3-feet tall, 24-inches square at the base, tapering to 17.5-inches at the top. The pedestal is supported on a 32-inch square base.
Philadelphia Pennsylvania USA Horizontal Dial 146
A 10 inch diameter horizontal dial on a 40 inch tall square marble pedestal with dedication plaque. Gnomon is missing.
Philadelphia Pennsylvania USA Vertical Dial 147
A vertical dial within a bronze sunflower held overhead in the outstretched arms of the bronze sculpture of two children.
Philadelphia Pennsylvania USA Horizontal Dial 148
Horizontal dial approximately one foot diameter mounted on old stone atop a 3 foot stone pedestal. It is sitting against north wall of the garden and not aligned in proper direction. Plaque at the base states "This sundial stood for over a century in the gardens of Dorchester House, Park Lane, London, England. Presented by The Soroptomist Club of Philadelphia, December 23, 1935". This may be true for the dial plate because the hour angles indicate a latitude of 51°, the London latitude. It may not be true for the gnomon, whose style angle is 40°, the Philadelphia latitude. Access by taking guided tour, $5; then ask for garden.
Philadelphia Pennsylvania USA Vertical Dial 149
On wall of the passage from hallway to kitchen inside the house, just for exhibition. 9.5 x 19 inches, rough wood painted in black, roman numerals from 8 am to 5 pm on 1.5 inches wide frame, it was for hanging on a declining wall. Black iron gnomon rod, 1 foot in length, is supported with iron vine which is fixed to a point on the dial plate about 1.5 inches from the noon line. Unfortunately, the gnomon seems twisted, so that it points down over the noon line, like those for dials facing true south. Admission fee: $5.00 for guided tour. No photo allowed inside.
Philadelphia Pennsylvania USA Horizontal Dial 150
A 21 inch diameter horizontal dial on three foot brick pedestal. Hour lines only. Gnomon reclined. Made in 1989 to commemorate Bicentennial of the General Assembly Presbyterian Church (USA). Visible through locked gates.
