The East Bay Hills [3] [4] refer to a 'fault ridge' of ancient rock on the south side of the East Bay of the Bras d'Or Lake, located on Cape Breton Island, Canada, and are an extension of the Appalachian mountain chain. The East Bay Hills lie in Cape Breton County.
The East Bay Hills rise to little more than 180 metres (590 ft), forming low ridges in an otherwise lowland landscape. These hill are largely uninhabited (by humans), and include the highest elevation point on Cape Breton Island south of the Bras d'Or Lake at Sgurra Bhreac with a commanding view of the Mira area and Atlantic Ocean to the south.
The East Bay Hills are an elongated block of Precambrian rocks and is composed of two rock types: primarily volcanic deposits of the Fourchu Group (ash and lava interleaved with marine sediments), but also granites. They are elongated northeast–southwest in accordance with the same prevailing trend of faults which dominates the geological structures of the North Bras d'Or Uplands. The southeastern margins are also faulted, in this case bringing the resistant Precambrian strata against late Carboniferous sandstones and siltstones. On the northeastern side the contact is with easily eroded Carboniferous Windsor Group strata, which were deposited directly against the blocks when they stood as islands in the Carboniferous Sea.
In form and structure the relief and elevations of the East Bay Hills reflect not only their geological setting, surrounded by rocks of varying resistance, but also their position on the low side of the planation surface. Precambrian rocks of equivalent resistance have created dominant uplands further north in Cape Breton, but here, where there was little uplift during the Tertiary, there was also minimal rejuvenation of erosional action and limited exposure of this hard core of old rocks.
The steepest slopes are found on the northwest side of the East Bay Hills, where soft Windsor Group rocks form a narrow band along the shore. The valley of Breac Brook, at the north end of East Bay Hills, appears to be an ancient coastal valley which was filled by Windsor Group deposits and is now being exhumed. The fault line on the southeastern margin can be seen in some areas (e.g., northeast of Oban) but in general does not form a prominent scarp slope.
In this part of Cape Breton south of Bras d'Or Lake, glaciation more than geological structure appears to have influenced drainage patterns. South of East Bay Hills the glacial direction is strongly northeast–southwest, in this case parallel to the fault which defines their southern boundary. [5]
The East Bay Hills have relatively flat plateau-like crests which are poorly drained. Most streams are located on the margins and are aligned northeast, reflecting the glacial direction. The hills contains several lakes and a few scattered raised bogs. [5]
Heavily podzolized Thom soils with a thick iron humate B horizon cover most of the hills. They are associated with Arichat soils (poorly drained, mottled, sandy loams), found where the relief is gently undulating or depressional. There are also small areas of peat. [5]
These hills are somewhat lower than the North Bras d'Or Hills and shade-tolerant hardwoods, although present, are not dominant. The East Bay Hills support instead mixed stands of Red Maple, White Birch, Yellow Birch, American Beech, Balsam Fir, and White Spruce. [5]
There are few moose in this area. Deer are found on side slopes in winter yards. There are a large number of eagle nests in stream ravines. [5]
The hills offer views north over Bras d'Or Lake, for example, where Highway 4 climbs above shore level near Irish Cove and Middle Cape. [5] Ben Eoin Provincial Park lies along the north edge of the hills. The Ben Eoin Trail (1.7 kilometres (1.1 mi) return) starts at the Ben Eoin Provincial Picnic Park and leads to a well cleared look-off of solid ground and large flat stone on a ridge of the East Bay Hills with a panoramic view of the East Bay of the Bras d'Or Lake 165 metres (541 ft) below. [6]
Small-scale farming is practised in some areas of the East Bay Hills. Fishing the waters of the Bras d'Or Lake and sporadic forestry have been economic activities in the past. Much of this area is now cottage country, and tourism plays a significant role in the local economy. In the early 1900s the mineral springs at Glengarry in Irish Cove were well known for their perceived healing properties, which drew local people as well as distant travellers. [5]
Cape Breton Island is an island on the Atlantic coast of North America and part of the province of Nova Scotia, Canada.
Cape Breton Highlands National Park is a Canadian national park on northern Cape Breton Island in Nova Scotia. The park was the first national park in the Atlantic provinces of Canada and covers an area of 948 square kilometres (366 sq mi). It is one of 42 in Canada's system of national parks.
Bras d'Or Lake is an irregular estuary in the centre of Cape Breton Island in Nova Scotia, Canada. It has a connection to the open sea, and is tidal. It also has inflows of fresh water from rivers, making the brackish water a very productive natural habitat. It was designated the Bras d'Or Lake Biosphere Reserve by UNESCO in 2011.
The Cape Breton Highlands, commonly called the Highlands, refer to a highland or mountainous plateau across the northern part of Cape Breton Island in the Canadian province of Nova Scotia.
Highway 105 in Nova Scotia represents the Cape Breton Island leg of the Trans-Canada Highway. It runs from the Port Hastings Rotary just east of the Canso Causeway in Port Hastings to the Marine Atlantic ferry terminal in North Sydney, representing a distance of 142 kilometres (88 mi).
The Mira River is a Canadian river located in eastern Cape Breton Island, Nova Scotia.

The Cobequid Mountains, also sometimes referred to as the Cobequid Hills, is a Canadian mountain range located in Nova Scotia in the mainland portion of the province.
Sgurra Bhreac, sometimes referred to as the Big Rock, is a Canadian peak in the East Bay Hills of Cape Breton Island, an extension of the Appalachian mountain chain in the province of Nova Scotia. Sgurra Bhreac is a prominent rock outcrop, rising 50 m (160 ft) from the northern edge of The Big Barren, between the Breac Brook and Glengarry Valleys, and is the highest point on Cape Breton Island south of the Bras d'Or Lake with its summit at 222 m (728 ft).

An inlier is an area of older rocks surrounded by younger rocks. Inliers are typically formed by the erosion of overlying younger rocks to reveal a limited exposure of the older underlying rocks. Faulting or folding may also contribute to the observed outcrop pattern. A classic example from Great Britain is that of the inlier of folded Ordovician and Silurian rocks at Horton in Ribblesdale in North Yorkshire which are surrounded by the younger flat-lying Carboniferous Limestone. The location has long been visited by geology students and experts. Another example from South Wales is the Usk Inlier in Monmouthshire where Silurian age rocks are upfolded amidst Old Red Sandstone rocks of Devonian age.
The geology of Massachusetts includes numerous units of volcanic, intrusive igneous, metamorphic and sedimentary rocks formed within the last 1.2 billion years. The oldest formations are gneiss rocks in the Berkshires, which were metamorphosed from older rocks during the Proterozoic Grenville orogeny as the proto-North American continent Laurentia collided against proto-South America. Throughout the Paleozoic, overlapping the rapid diversification of multi-cellular life, a series of six island arcs collided with the Laurentian continental margin. Also termed continental terranes, these sections of continental rock typically formed offshore or onshore of the proto-African continent Gondwana and in many cases had experienced volcanic events and faulting before joining the Laurentian continent. These sequential collisions metamorphosed new rocks from sediments, created uplands and faults and resulted in widespread volcanic activity. Simultaneously, the collisions raised the Appalachian Mountains to the height of the current day Himalayas.
