Nature
Mont Saint-Hilaire is a prominent mountain in Quebec’s Montérégie region, rising sharply above the plain near the Richelieu River and long serving as a regional landmark. Formed as an intrusive mountain during the Cretaceous and later exposed by erosion, it is renowned for exceptional mineral richness, with more than 366 mineral species found there, including 50 first identified at this site. It also protects important remnants of Saint Lawrence Valley lowland forest and fragile cliff ecosystems. Known to Indigenous peoples long before European settlement, it later became a tourist destination and, under Andrew Hamilton Gault and McGill University, much of it was preserved as a protected natural area.
