According to accompanying information,"Gnomon, featured in Fleetwood Park’s perennial garden, is inspired by the notion of a sundial marking time.

Vernon British Columbia Canada Analemmatic Dial 933
On a barren hill sits a simple analemmatic dial in an area cleared of brush. Rather than standing on a walkway that is common for outdoor analemmatic dials, this one uses a movable poles gnomon guided in a slot. The slot is surrounded by an analemma with dates allowing the pole to be adjusted for the date of viewing. The central date scale assembly is wooden. The dial hour marks are concrete disks with glass mosaics on top created by local artist Connie Vetter-Johnson. Above the noon hour mark is a larger disk with a glass mosaic image of a hawk. Photographs of the site hint that some of the hour marks may have been inadvertantly moved out of position.
 
 
Vancouver British Columbia USA Horizontal Dial 932
This was once a very beautiful sundial sitting on a short concrete pedestal. Now it has a missing gnomon and the dial color is uniformly aquamarine except where the coating has been rubbed away to reveal a white substrate. Tapping the dial face makes a dull sound suggesting the dial is not metal and may be hollow. A possible explanation is that the dial could be made of some kind of cast resin or fiberglass and was then spray-painted. The dial face itself is elegantly sculpted into five sectors, showing clusters of flowers, berries and fruits, creating a pronounced 3D effect. Because of this, the hour lines are reduced to short ticks at the edge of the dial face. The dial shows solar hours, marked off using Roman numerals.
 
 
Vancouver British Columbia Canada Equatorial Dial 931
A simple but elegant and well-executed bronze equatorial dial by renowned local sculptor Gerhard Class. It is about 24-inches in diameter and is mounted on a 16 x 16 x 36-inch plinth of nephrite jade, damaged at one corner. The gnomon has a central slit and can be rotated about the polar axis to create a narrow beam of light for precise reading of the sun's position. The dial shows local solar time plus one hour, corresponding to Daylight Saving Time. The dial's construction is technically perfect but, sadly, the dial appears to be misaligned with the gnomon axis pointing 7 deg west of north.
