[1] Mont Shefford is 526 metres (1,726 ft) 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.
