The Cairn and the Time Capsule
A practical approach to physical history by Steve Stewart and Lorenzo Simeon
The story that has come down to us from 1970 was summarised in our(with Millie Watson) recent book:
The presence of Prime Minister Trudeau and six members of his cabinet in 1969 was already adequate indication that the federal government recognised the importance of Abbotsford to Canada’s aviation and aerospace aspirations. In his opening speech, he had explicitly described the show as being Canada’s showcase to the aviation world. The phrase was repeated in a letter received from Don Jamieson in December. He went on to say ‘I would therefore suggest that you name your air show next year as ‘Canada’s 1970 National Air Show’’. With this endorsement, the show officially became the country’s national air show. Minister Jamieson said ‘I would endorse this exhibition as being an excellent occasion for any Canadian or foreign company to display its aviation products and services’. To mark the development, Glenn Matthews designed a new airshow insignia, a limited edition airshow coin was minted (original price $2), and a souvenir postcard produced (10c). As well, at Don Jamieson’s suggestion, a project was started to erect a stone cairn. Rocks were flown in from every Canadian province and ‘every quarter of the globe, including the USSR’, pieces of the old London Bridge and rocks from the Matterhorn. A copper time capsule buried in the cairn contained messages from Prime Minister Trudeau, opposition leader Robert Stanfield, other Ministers, and President Richard Nixon. Dedication would be at 1pm on August 7th, the first day of show, by Jamieson and Fraser Valley East MP Jerry Pringle. The cairn and time capsule were scheduled to be opened after 50 years, on August 7th 2020.
The cairn was originally located just outside the airside entrance to the customs office of the terminal, which in 1970 was located in Hangar Number Two. Since then, over the past 50 years, as terminals have been built, moved, redeveloped and relocated, the cairn has been moved at least three times, and it no longer stands on its original base. The language used to describe the time capsule’s location was not precise. Was it in the cairn itself, or buried beneath it? Had they parted company at some point? Back in February, we invited Justin Trudeau to officially open the cairn and the time capsule – which seemed fitting, given his father’s role in their creation. He has not replied yet. However, we needed to be certain that we can open the time capsule on cue on August 7th.
In December we removed the plaque from the front of the cairn, removed cement and concrete from behind it, and failed to find the time capsule. The plan was to come back in March, but that was foiled by external forces. Lorenzo Simeon and I returned to continue removing concrete in early May. We removed rocks from the back, and drilled and jack-hammered from front and back. But our holes joined up, after finding only concrete and steel in between.
The situation was not promising, and August is fast approaching. We arranged to use ground penetrating radar. We contacted a local stone mason in case he could provide insight. We asked Chilliwack airport about how their cairn was constructed. We asked Langley concrete about the pre-cast concrete core, around which the rocks are built. We contacted the Freemasons about the marks associated with the rock from the Old London Bridge. We asked the national archives in Ottawa to look for records, because the airport was a federal facility and the cairn was built on the instructions of the Minister. And Millie Watson stepped up her campaign to contact AFC Members from long ago. We were prepared to hollow out the entire monument one chip at a time, while leaving its façade intact. And we were prepared to excavate at the cairn’s previous locations.
But before launching the wholesale jack-hammering campaign, we tried some logic. During the 1970 ceremony, one convenient way to have placed the time capsule (other than directly behind the plaque) would have been to almost complete the cairn, then pop in the time capsule, and finish it off with a concrete cap. So we drilled and jack hammered up under the cap, but we got right past the centre without finding anything. Bear in mind that we only knew the capsule was made of copper, without knowing its size or shape. There was not much remaining unexplored volume. Our last logical option was to pop off the whole cap and hope for something to emerge. It did. The cap came off with a copper cylinder still embedded in the cement. It is 10 inches long and 3 inches diameter. The damage from our drilling revealed printed papers inside, but the papers are undamaged. Who knows what those papers will reveal?
Before August we will reassemble the cairn, with the time capsule inside, so that it can be easily cracked open on the given day.
Later, the time capsule will be replaced in the rebuilt cairn, along with a new time capsule from 2020. They will not be opened until August 7th 2070.
After the opening, we will publish a fuller story of the cairn, along with the contents of the time capsule. And there will be pictures.
