The casque for Image 9 and Verse 5 is thought to be buried somewhere in or near Montreal in Canada.  The City of Montreal maintains a huge archive of over 7,300 low-altitude aerial photos taken between 1960 and 1992.  The key thing about these photos is that they are oblique.  Rather than the standard aerials that are taken from more-or-less directly overhead, these photos were taken at an angle from the side.  This allows us to see tree bases under the tree canopies and it allows us to see thin things, like chainlink fences, that would be invisible in a standard aerial.

There appear to be 8 sets of photos that are relevant to Saint Helen's Island.  The photos that were taken in 1969, 1974, and 1976 capture the island shortly after Expo 67 and a few years before Byron Preiss visited.  The photos taken at the Floralies in 1980 are closest to the time of the visit.  The photos taken in 1986, 1988, and 1989 capture the island falling into disrepair after the end of Man and his World.  Changes that are not shown in these photos, such as the compass disk embedded in the ground at the southern tip of the island, must have been made after 1989 and are therefore irrelevant to the puzzle.

Searchers who are interested in Montreal locations other than Saint Helen's Island can download a database of all the photos from the link above and go through the different location descriptions.  (If you find any that are relevant to The Secret, please create a page or send us a note!)

The links below go directly to the archives of the City of Montreal.  (We are not hosting the photos on the wiki.)  Each set of photos is identified by the number, location, photographer, and date.  If you use any of these photos elsewhere, please credit the individual photographer and the Archives of the City of Montreal.

Île Sainte-Hélène - piscine et terrain de sports / Louis-Philippe Meunier / 31 juillet 1969  (31st of July, 1969)

Île Sainte-Hélène / Rh√©al Benny - 24 septembre 1974 (24th of September, 1974)

These photos were taken seven years after Expo 67.  The seven photos that make up the series show a flyby of the southern tip of Île Sainte-Hélène as the plane is traveling from east to west.

Vue d'ensemble de la Terre des Hommes, de l'Île Sainte-Hélène, de l'Île Notre-Dame et de La Ronde
/ Rh√©al Benny / 2 août 1976  (2nd of August, 1976)

These photos were taken during the 1976 Man and his World summer exposition, just two months after a fire severely damaged the geodesic dome in the Biosphere.

VM94-B253

Floralies / R√©al Benny / 21 août 1980  (21st of August, 1980)

These photos were taken during the 1980 Floralies and they are probably the closest photos we have to the time when Byron Preiss buried the casque.  Unfortunately, the Floralies was largely staged on Notre Dame Island, so we only have a few views of Saint Helen's Island.  The date of these photos is also just over a month before the staging of the 1980 Canadian Grand Prix on September 28, 1980, and some of the pictures show preparations for the race.

Îles Sainte-Hélène et Notre-Dame; Centre-ville vu du Sud-Ouest / Martel / 23 avril 1986  (23rd of April, 1986)

These photos were taken just as the long northern winter was ending.  The snow is all gone, but the trees have not yet started to leaf out, so we get a good view of the ground.

Southern end of Saint Helen's Island, looking northwest to northeast.       The striking thing about the first four photos is that we have a clear view of the ground but we do not see the white stone or white stripes that should be there at the southwest corner of the Place des Nations.  (Compare these photos to VM94-B208-013.tif , taken in 1976.)  Did the stone disappear?  Or is everything white obscured by dust and gravel from the winter snowmelt?  It doesn't really make sense that someone would take the stone and then bring it back later.

La Ronde, Îles Sainte-Hélène et Notre-Dame / R. Martel / 21 juin 1988  (21st of June, 1988)

These photos were taken during several airplane loops above the two islands.  To make this page a little more manageable, we've omitted the first 21 photos that just show La Ronde, the amusement park at the north end of Saint Helen's Island, taken from a number of different angles.

Vues a√©riennes des Iles / R√©jean Martel / 26 août 1989  (26th of August, 1989)

Note that some of these images (such as #41) have the negative flipped, so they show the mirror image of the real layout.
