There have been many #gypsum quarries in #Hants over the years, including several in the #KemptShore/Cheverie area.
There were two quarries near #Cheverie that operated in the 1900s, the Cove and Upper Head quarries. The Cove Quarry was close to the shipping pier. #nspoli#cbpoli
Erosion by waves created tunnels into the deposit that were used to access the #gypsum. The gypsum was drilled with hand augers, loaded onto carts and hauled to a stockpile by the pier where it was loaded onto barges for shipping. #nspoli#cbpoli#novascotia@RegMunWWH#nshistory
The Upper Head quarry was about 100 yards east of the pier along the shore.
In 1912, there were 40 men employed at the two quarries. Some of their #gypsum was used as fertilizer by peanut growers in the United States. #nspoli#cbpoli#novascotia@RegMunWWH#nshistory
There were two gypsum quarries in #KemptShore but little is known about them due to lack of records. One is easily identifiable because today it is the Kempt Quarry Recreation Site and a beautiful lake. A second quarry was nearby, a little to the west. #nspoli@RegMunWWH
The water at the Kempt Quarry Recreation Site is clear and clean (and tested regularly by the #WestHants Recreation Department) and is a great spot for swimming. It has rocky ledges to leap off and a shallow area for kids. #nspoli#cbpoli#novascotia@RegMunWWH#nshistory
The specific question we were asked is whether there is old mining equipment at the bottom of the Kempt Quarry Recreation Site lake, leftover from the historical operation. We checked with the good folks at the Municipality of West Hants and they tell us the answer is no. #nspoli
They actually hired a diver a number of years ago to investigate the lake and no old equipment was found.
Historical mines/quarries usually moved equipment to new sites when an operation closed – it was valuable, after all. However, they did sometimes abandon old equipment.
This clearly is not acceptable today and modern industry standards and government regulation prevent it now. But back then, it was not unusual for many industries to abandon equipment, i.e. old forestry equipment can also sometimes be found in the woods, etc. #nspoli@RegMunWWH
It used to be common for people and companies to dump waste in the woods and waterways. Fortunately, industry standards – and society’s standards – have come a long way since then! #nspoli#cbpoli#novascotia@MLAChuckPorter@RegMunWWH#nshistory

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
