The Landforms & Geology of Bruce Peninsula
The Niagara Escarpment runs from Niagara Falls to Tobermory.Approximately 400 million years ago,this area was covered by a shallow tropical sea with life in form of plant type animals,crustaceans,living corals and mollusks.The sea began to dry up later on which resulted in the minerals to dissolve and become concentrated.The Magnesium in the water absorbed into the limestone that created a harder and slightly different rock called dolomite.The Bruce Peninsula is part of the landform region of Great Lakes-St.Lawrence Lowlands which is the smallest landform region seperated into two parts.In this area,the landforms you would find would be waterfalls,dry rock plains,and rugged cliffs.You would find sedimentary Rock from the paleozoic era underneath the bedrock.
The Landforms & Geology of Mixedwood Plains
Until the recent continental ice sheet retreat 11,000 years ago,the Mixedwood Plains Ecozone had been buried underneath a kilometre of ice. Following the ice age, the St. Lawrence and lower Ottawa valleys were covered by the Champlain Sea for another 1 200 years.Beneath the urban centres and agricultural fields are mesozoic and palezoic sedimentary rock.Striking physical features break up the near level of gently rolling plains for the ecozone.The most prominent is the Niagara Falls Escarpment from Niagara Falls to the northern tip of the Bruce Peninsula and Manitoulin Island.The landforms found in this area would be waterfall's,river's,plain's and wetland's.
