The cache initially contained:
- A log book and two pencils
- A Tim Horton’s card for the FTF
- A Celtic Circle of Life Geocoin
- An OLG Gold Bar Key Ring
- Three World Maritime Day zipper pullls
- A beaded zipper pull
The plan for this cache seemed simple. It is located due north of the posted co-ordinates. The catch is that in this case due north is defined by the direction of a shadow from a vertical stick at midday on October 12. A sundial works by True (or apparent) Solar Time whereas we keep time according to Mean Solar Time. The difference between True Solar Time and Mean Solar Time requires us to correct the time we read on a sundial according to the Equation of Time. The equation of time is sometimes reproduced on sundials, e.g. on October 12th it is necessary to add 13 minutes and 18 seconds to the time we read on a sundial.
People are generally not aware that for many years this part of Canada operated on Montebello Time. The reason for this was simple; Montebello in Quebec is very close to the 75 degree West meridian. This meridian is the reference longitude for Eastern Standard Time. Montebello today celebrates their location with the equatorial sundial that you see as you drive through the village of Montebello, as shown in the following photograph. It is worth noting on this photograph, as with any sundial, that the lower row of hours represents Daylight Time and is therefore displaced relative to the Roman Numerals for Standard Time.
In order to find the cache it is necessary to determine the direction from the posted co-ordinates of a sundial shadow on October 12th, taking into account the longitude of the posted co-ordinates relative to the reference longitude for our time zone and the effects of Daylight Savings Time. It is sufficient to round the bearing in degrees to the nearest whole number of degrees. Once you have the direction the distance to the cache is BAC metres where ABC is the square of the number of brackets attaching the railing to the concrete on one side of the bridge at the posted co-ordinates.
Access to this area is by means of the recently extended pathway system that runs north south parallel to the Airport Parkway, from Hunt Club Road to the Walkley Road transitway station. The access from the South Keys Mall is via the tunnel at the South Keys Transitway station.
