Familiar Landscapes


One of Campobello Island’s most photographed lighthouses is built on volcanic rock. Silurian diabase and gabbro at East Quoddy Head provide a rugged foundation for the picturesque buildings.

Kingston Peninsula

The Kingston Peninsula north of Saint John separates the Kennebecasis and St. John rivers as they flow toward the Bay of Fundy. The peninsula also provides the name for the Kingston Terrane, its Silurian volcanic rocks a remnant of volcanic islands produced during the subduction of an ancient ocean floor. The rocks are well hidden under the forests and farmlands of the peninsula. Highway 7 from Saint John to Welsford exposes outcrops of the same volcanic terrane on the west side of the Saint John River.

Florenceville-Bristol, Trans-Canada Highway

Much of New Brunswick’s Silurian geology lies hidden from view, covered by forests in the Province’s northwest region. Travellers on the Trans-Canada highway north of Woodstock are most likely to see rocks deposited in the Silurian seas. Tens of kilometers of road outcrops from Woodstock to Edmunston expose grey tilted and folded layers of the Ordovician to Silurian seafloor. Recent highway construction has exposed tall roadside outcrops that reveal the crumpled sedimentary rock.
