Description:
  • 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. The new dial was unveiled during the 2003 NASS Conference Sundial Tour.
