Snow in the quarry, but which one?

Various sources have been marvelling recently over the mass of snow lingering in the St-Michel quarry, but this CBC piece says the canyon in question used to be the Miron quarry, which I think is mistaken. The Miron quarry became the Complexe environnemental de St-Michel and, later, Frédéric-Back park. The quarry used by the city for snow is, I believe, the old Francon quarry, further east, and with no plans in the works to turn it into a park like the other.
