Calgary Alberta Canada Horizontal Dial 661
A 9 inch diameter horizontal dial of Welsh green slate with brass gnomon. Hour lines show DST with longitude correction. Declination lines are shown for solstices and equinoxes. The gnomon includes a NASS logo. The dial sits atop a stone plinth with 12 inch diameter top. The original Sundial of Hope, sponsored by Child Find of Alberta, was placed in 1993 on an original plinth dating to before WW2. The simple dial installed in 1993 had been vandalized and the gnomon was missing. Roger Bailey designed and built this replacement dial to commemorate the 10th Anniversary of the founding of NASS.

Vancouver Washington USA Equatorial Dial 659
A 2 meter diameter ring equatorial dial of welded anodized aluminum plate. The dial face shows Arabic numerals with hour and quarter-hour marks. This face can be moved for longitude correction and DST, and was originally adjusted to correct periodically for EOT. In 2009, the original straight gnomon was replaced with an analemmic gnomon, eliminating the need to adjust or correct for EOT.
 
 
Redlands California USA Vertical Dial 658
A 60x40 foot vertical dial of stucco, wood and brass, filling the south exterior wall of the building. Roman hour numerals show PST; Arabic hour numerals show PDT. Summer and winter solstice and the equinox lines are shown; the shadow of a nodus on the gnomon indicates the date. Dr. Nordgren explains that the shadow of the 10-inch diameter nodus "is just the right size to take into account periods when sundials are fast or slow relative to clock time. When dials run their slowest, the leading edge of the nodus shadow gives the accurate time. During periods when dials run their fastest the trailing edge gives the accurate time." Dr. Nordgren was among the seven designers of the sundials used on the NASA Mars Rovers in 2004.
 
 
Gold Canyon Arizona USA Horizontal Dial 657
Built as an Eagle Scout project, this 10 x 5 foot semicircular concrete and steel dial features a 3 foot tall figure of a coyote as the gnomon. The tip of the coyote's nose functions as a point-in-space gnomon. The figure is placed well forward, limiting the times and dates the nose-tip shadow will fall within the hour circle to about 9 am to 3 pm on dates near the summer solstice.
 
 
Colwood British Columbia Canada Horizontal Dial 656
A 12 inch octagonal stone horizontal dial with Roman hour numerals.

This historic dial dates from the original Pendray House on the Havenwood, built in 1928. The dial was in poor condition and the gnomon was missing. In July, 2009, NASS member Roger Bailey cleaned the dial, highlighted the markings and fabricated and installed a new brass gnomon.
