Visible Trace of the Saint-Pierre River

The [Saint-Pierre River](https://en.wikipedia.org/wiki/Saint_Pierre_River_%28Montreal%29) was one of Montreal's important historic watercourses but has almost entirely disappeared from the visible city. A short trace of its former route can still be read near the Côte-Saint-Paul locks, making this one of the best places to map the lost river on the surface.
