Mont Shefford is a Monteregian Hill located in Shefford in the Estrie region of Quebec, Canada.[1]
Mont Shefford is tall, and was home to the Ski Shefford ski resort which closed in 2006.[2]
Mount Shefford was formed some 125 million years ago during an underground intrusion of magma. This magma did not reach the Earth's surface and remained in a deep freeze. The mountain appeared following the erosion of nearby sedimentary rocks by glaciers. The sedimentary rock was more fragile than the metamorphic rock formed by the contact of the magma and the surrounding sedimentary rock.
