Hopewell Rocks are rock formations located at the upper reaches of the Bay of Fundy near Hopewell Cape Bedrock types range from 1 billion to 200 million years old. Much of the bedrock in the west and north derives from ocean deposits in the Ordovician that were subject to folding and igneous intrusion and that were eventually covered with lava during the Paleozoic peaking during the Acadian orogeny During the Carboniferous era about 340 million years ago New Brunswick was in the Maritimes Basin a sedimentary basin near the equator Sediments brought by rivers from surrounding highlands accumulated there; after being compressed they produced the Albert oil shales of southern New Brunswick Eventually sea water from the Panthalassic Ocean invaded the basin forming the Windsor Sea Once this receded conglomerates sandstones and shales accumulated the rust colour of these was caused by the oxidation of iron in the beds between wet and dry periods. Such late carboniferous rock formed the Hopewell Rocks which have been shaped by the extreme tidal range of the Bay of Fundy In the early Triassic as Pangea drifted north it was rent apart forming the rift valley that is the Bay of Fundy Magma pushed up through the cracks forming basalt columns on Grand Manan Topography.
