Mount Carleton Provincial Park

The Devonian Period witnessed the building of the Appalachian Mountains. The Provinces’ Appalachian Range Route, a highway-driving trail, follows the remnants of an ancient mountain chain that stretches along the east coast of North America and continues into Europe as the Caledonide Mountains.

At 820 metres, Mount Carleton in the remote highlands of north-central New Brunswick is the highest peak in New Brunswick and the Maritime Provinces. The mountain was named after Thomas Carleton, New Brunswick's first lieutenant governor. Mount Carleton Provincial Park is part of the Canadian portion of the International Appalachian Trail. The mountain is a monadnock, an erosional remnant of resistant igneous rocks that remained after an ancient surface was uplifted to form a plateau, and subsequently worn down over millions of years of erosion by wind, water and glacial ice. It is made of silica-rich rhyolitic and basaltic volcanic rocks that erupted during the early Devonian about 400 million years ago.
