The mineral occurrence isn’t of any significance – it’s a small outcrop of galena, sphalerite and pyrrhotite in limestone, and marcasite in small quartz veins – but it’s as far north as you can go in #NovaScotia. #nspoli#cbpoli#capebreton
What is interesting is St. Paul Island itself. It's in The Cabot Strait, at the entrance of The Gulf of St. Lawrence, about 14 miles from Cape Breton. #NovaScotia#nspoli#cbpoli#capebreton
It is an extension of the Appalachian Mountains, which started forming 480 million years ago as North America and North Africa collided. The Appalachians ran 2400 kilometres from Newfoundland to Alabama, right through the Maritimes. #NovaScotia#nspoli#cbpoli#capebreton
The Aspy Fault, a prominent feature of northern Cape Breton’s geology, extends north from the #CBHighlands and passes just to the east of St Paul's underwater. #NovaScotia#nspoli#cbpoli#capebreton
In fact, it carries on to Newfoundland and during supercontinent Pangea, when #NovaScotia was connected to western Europe, the Aspy Fault was likely connected to Scotland's Great Glen Fault, home to Loch Ness.
St. Paul is known as the Graveyard of the Gulf. #nspoli#cbpoli
It's often fog-bound cuz of the different temperatures of the Gulf Stream and Labrador Current which meet in the area. The island therefore posed a significant hazard during the Age of Sail with its location in the middle of shipping routes. It had 350 ships wreck on its shores.
For example, a three-masted barque called the Jessie left Charlottetown on December 24, 1824 and was caught in a snowstorm which drove her onto St. Paul Island. The survivors’ fires could be seen from the mainland but because of pack ice, no rescue vessel could reach them.
They survived nearly 11 weeks but eventually succumbed to starvation. Being marooned on the island meant almost certain death back then due to the lack of animal life on St. Paul and the harsh weather in the Cabot Strait. #NovaScotia#nspoli#cbpoli#capebreton
Back in Charlottetown the fate of the Jessie was unknown until a French sealer who had visited St. Paul Island in the spring was apprehended by Mrs. Mackay, the wife of the Jessie’s owner, who saw the man wearing her husband's coat. #NovaScotia#nspoli#cbpoli#capebreton
She pulled the coat open and found her husband’s initials, which she had sewn into the lining. Police were notified and the man explained how he and others had visited the island in the spring, as fishermen often did, to hunt seals and salvage shipwrecks. #NovaScotia#nspoli
A ship was sent to the island and Donald Mackay's body was recovered along with his diary. The final entry was on March 17 and it indicated that he was the last survivor. Jessie’s Cove takes its name from the wreck. #NovaScotia#nspoli#cbpoli#capebreton
The ongoing loss of life compelled the government of Nova Scotia in 1831 to place a frame house and provisions at a cove on the southeast side of the island to help shipwreck victims. After the house had been built, workers cut a road across the island and... #NovaScotia#nspoli
...discovered a small lifesaving station on the western shore that the government of New Brunswick had built and staffed with two men and their families. The two provinces had had no idea what the other was doing.
In 1839, two lighthouses were built. #NovaScotia#nspoli#cbpoli
In the north one was built on a small island that is separated from the northeast end of St. Paul Island by a narrow passageway known as The Tickle or The Tittle. Another was built on the southwest point of the island. #NovaScotia#nspoli#cbpoli#capebreton
A lifesaving station was also built at Atlantic Cove, about mid-island on the eastern shore. Both lighthouses were octagonal wooden towers 40 feet tall.
The wooden lighthouse in the northeast was replaced with a concrete tower in 1962. #NovaScotia#nspoli#cbpoli#capebreton
The lighthouse in the southwest burned down in 1914 and was replaced by a cast iron, cylindrical lighthouse in 1915. This was in turn replaced by an automated system in 1964.
The cast iron lighthouse (the 1915 version) is surprisingly well-travelled. #NovaScotia#nspoli#cbpoli
Designed to be easily-moved, it was fabricated at the Dominion Lighthouse Depot in Prescott, Ontario, and shipped by train and boat to St. Paul Island. #NovaScotia#nspoli#cbpoli#capebreton
It was in the southwest corner of St. Paul Island from 1915-1982 and then at the Canadian Coast Guard base in Dartmouth from 1982-2011. In 2011, it was moved to #Dingwall, Cape Breton, where it is currently at the St. Paul Island Museum. #NovaScotia#nspoli#cbpoli#capebreton
St. Paul Island also hosted a radar station in WWII and a Marconi wireless station.
The island has been uninhabited for decades. #NovaScotia#nspoli#cbpoli#capebreton

For example, an e-car has 183 pounds of copper wiring in it because copper is used in every major component from the motor to the inverter and the electrical wiring. There is about four times more copper in an e-car than in a car with an internal combustion engine.
There are about 400 electric cars on Nova Scotia roads - a total of over 73,000 pounds of copper!
An electric car uses 25-50 grams of silver, so Nova Scotia’s 400 e-cars contain about 15,000 grams of it.
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. (The terms cement and concrete are often used interchangeably, but cement is actually an ingredient of concrete... #nspoli
...Cement is the glue that holds concrete together.)
Reinforced concrete means the concrete is poured over a frame, usually steel bars, that give the structure greater strength. #nspoli
The short answer is yes, sinkholes are real but no, they are not a major risk and should not prevent you from enjoying outdoor activities.
Most natural sinkholes are caused by groundwater naturally eroding rocks like gypsum, salt and limestone which are water-soluble. #nspoli
The water erodes the rock, leaving an underground cavern. Eventually, the weight of the rock and earth above the cavern causes the sinkhole to form. Sinkholes can form either gradually (i.e. a small depression appears and perhaps grows larger over time) or by sudden collapse.
The New Campbellton coal mine was opened in 1862 by Charles J. Campbell, a former Member of Parliament, Member of the Legislative Assembly and executive council member. The community had been named Kelly’s Cove but was changed to New Campbellton in 1862 in honour of Mr. Campbell.
A sample of New Campbellton’s coal was sent to the 1865 Dublin Exhibition and “was very favorably noticed by the Judges,” according to a report. #nspoli#cbpoli#novascotia#capebreton#nshistory
Mining built #NovaScotia! #Halifax was founded in 1749 and its first court house is reported to have been built by 1754 on the northeastern corner of Buckingham + Argyle streets. After the building burned in 1789, the courts were temporarily housed in various buildings. #nspoli
In April 1851 a bill to provide Halifax with a county court house was passed. Mr. H.G. Hill, a prominent #Halifax architect, prepared a plan for a wooden building.
However, since the records of the county, wills, deeds and other papers of public office were... #nspoli#novascotia
...to be stored in the court house, it was important that the building be fire-proof. Also, a number of serious fires in #Halifax in 1857 led to the passage of a bylaw that required large buildings be made of stone or brick, so Hill's plans for a wooden building were abandoned.
The Sullivan Creek #coal mine, before and after!
It's one of several mines reclaimed around #AlderPoint#CapeBreton in the late 1900s/early 2000s - examples of how mining makes temporary use of land and then land can be used other ways. #nspoli#cbpoli#novascotia@JaimeBattiste
The first mine in the area was the Scotia Mine, or #NovaScotia Steel & Coal Company No. 4 Colliery, on Toronto Road, which operated on the Sydney Main (Harbour) Seam from 1915 to 1921. #nspoli#cbpoli#novascotia@JaimeBattiste
Coal quality and structural issues (including water inflow) plague the Harbour Seam west of Florence so upon closure of the colliery, production on the Harbour Seam was limited to the Company’s No. 3 Colliery in Florence, which had opened in 1902... #nspoli#cbpoli#novascotia
