A deep scar on the mountain’s flanks, the quarry illustrates the effects of human activity. Serving as a reminder of our collective choices and economic development, the quarry’s impacts over the years have been appreciated by some and deplored by others.
Quarry operations led to the discovery of a wealth of minerals, many of which can be found nowhere else. Indeed, Mont Saint-Hilaire is one of the world’s ten richest mineralogical sites.
Yet highly coveted rock and gravel from the quarry have to be dug out and used responsibly to minimize the impact on mountain ecosystems and the landscape’s natural beauty.
