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.
 
 
Marshall North Carolina USA Equatorial Dial 642

Mounted on a concrete pedestal marked with city name and builder's mark. The pedestal is also marked with Marshall town map coordinates 35.79° N, 82.68° W, which are not the precise coordinates of the dial. Weathered finish is green enamel paint on steel. The concrete pedestal is marked with Marshall city name, builder's mark and approximate coordinates.
 
 
Pittsburgh Pennsylvania USA Horizontal Dial 641
A 12 inch octagonal carved sandstone horizontal dial with Roman hour numerals from 4 AM to 8 PM. The gnomon is missing. Dial face includes carved figures of a snake and a thistle and is marked latitude 40 35. The 1763 date ascribed to the dial's origin is coincident with the relief of the siege of Fort Pitt during Pontiac's Rebellion in that year. The 42nd and 77th Regiments of the Highland Guard and the 60th Regiment of the Royal Americans defeated the Native forces (Delaware, Shawnee, Mingo and Huron Tribes) at the Battle of Bushy Run in August, 1763, successfully quelling the Indian uprising in Southwestern Pennsylvania. The Highland Guard is artistically represented on the sundial by the thistle and the Royal Americans by the snake. Although the assignment of the 1763 date to the dial is not conclusive, the history of Fort Pitt, together with the design elements seen on the sundial and the location of its discovery, provides a plausible conclusion. This dial is reported to have been found at the site of the Fort Pitt Block House during its 1894 restoration by the Pittsburgh Chapter of the Daughters of the American Revolution who still own and preserve the structure and the sundial as a private museum. The Block House is the only surviving structure of Fort Pitt. Following the sundial's discovery in 1894, the dial was housed in the archives of the Carnegie Museum in Pittsburgh until 1916 when it was placed on a pedestal on the grounds of the Fort Pitt Block House for display. The dial was unfortunately exposed to acid rain then later covered with protective glass (later Plexiglas) that inadvertently accelerated its deterioration. Fortunately, an excellent picture taken between 1894 and 1900 shows the dial was in good condition when originally recovered. The dial was moved to a display case inside the Fort Pitt Block House in 2006. Today, the dial face is grainy and light gray. The reverse side is an irregular brownish gray that features an arrangement of holes that formerly served to mount the dial; four smaller holes marked by rust stains likely date to the 1980s when the dial was placed on a new, square granite pedestal. The dial face may be covered with a slip coating that was carved to produce the dial features. Measurement and analysis of the sundial hour line angles by Roger Bailey of NASS shows the dial was correctly designed for the latitude of Fort Pitt and even included a noon gap to correct for the thickness of the (now missing) gnomon.
 
 
Hastings Minnesota USA Analemmatic Dial 640
A 5x3 meter analemmatic dial of natural limestone rocks with red flagstone and white limestone for month markers. Arabic hour numerals and month names are sandblasted into the stones.

Great Falls Virginia USA Horizontal Dial 633
A phosphor bronze horizontal dial whose face is 17.7 inches across four rounded cruciform arms. Designed, made and presented by Tony Moss to commemorate the establishment of the first English settlement at Jamestown on May 14, 1607. The most striking feature is the inclusion of reproductions of the King James Great Seal of the English Virginia Company. The "navette" (little boat) shape of the seal is also reflected in a similar shape for the dial itself. These "English" features are balanced by an American input in the form of the "Celebrate Virginia" logo and that of the local Analemma Society that co-funded the pedestal along with Fairfax County Park Authority. A unique rounded-cruciform shape encompasses all the above elements together with the NASS logo and appropriate inscriptions. The dial is calibrated in 3-minute intervals and quarter hours. Square classical pedestal in reconstituted limestone made by Haddonstone UK. Pedestal is placed in a paved and railed area around the dial. A remarkable steel "safe" is provided to protect the dial and pedestal from theft or damage.
