Former #mines and #quarries often become parks and protected areas. This thread shows some examples in #Halifax, #Dartmouth, #Shelbourne, #Truro, #LunenburgCounty and #KemptShore.

#KiwanisPark in #Truro was developed as a gravel pit in the 1930s to help build Route 2. Like a lot of former pits and #quarries, the site has filled with water and become a natural oasis in the heart of the town.

Former mines and quarries are often hidden in plain view! #PointPleasantPark contains 50+ former quarries. The stone was used to build walls and forts in the park. For example, slate from the #QuarryPond helped build the #MartelloTower.

370 million-year-old "Scotia Grey" #granite from the #Shelburne Island Park #Quarry helped build many #NovaScotia buildings including Shelburne Post Office and the old @chronicleherald building.
Today, the quarry is part of the Islands Provincial Park.

@chronicleherald #Granite from #TerenceBay was used in many heritage buildings in the 1800s and early 1900s. This lovely former quarry is now part of the #TerenceBayWildernessArea.

@chronicleherald #Gypsum quarrying began in #Hants in the 1700s when farmers exported it as fertilizer. There have been many quarries in the area since, including 2 in #KemptShore near #Cheverie.
Now the Kempt Quarry Recreation Site is a beautiful lake.

@chronicleherald @MLAChuckPorter #ShubiePark in #Dartmouth contains a former quarry that is now a baseball field and campground. Former mines and quarries are often hidden in plain sight!

@chronicleherald @MLAChuckPorter Merv Sullivan Park in north-end #Halifax is often called The Pit by people who may not realize that it was actually a gravel pit! Today it’s a lovely park and baseball field.

@chronicleherald @MLAChuckPorter Former #mines and #quarries often become parks and protected areas - like #TheOvens, where #gold was discovered in 1861! The gold rush left this beautiful park and campground with a fascinating history. People still love panning on the beach.

@nsgov announced new rebates for electric vehicles yesterday. Mining makes #greentech like electric cars possible because they are mostly made of minerals and metals.
#nspoli @KeithIrvingNS @IainTRankin @NS_Energy_Mines @ns_environment @ChenderMLA @AllanMacMaster @MLAChuckPorter Image
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.

The Morris Street Engine House has been declared a municipal heritage property!
#Halifax’s Fire Station #2, as it is also called, was built 1907-08 of reinforced concrete.
Here's the story!
#nspoli @HFXFireHistory @HRMFireNews @hfxfire @HFXFirefighters @hfxgov @MikeSavageHFX
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.

We love getting questions about mining, minerals and geology! We were asked about sinkholes and whether they are a risk when walking in the woods.
#nspoli #cbpoli #novascotia #capebreton @oxfordsinkhole ImageImage
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 Image
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. Image

We love getting questions about mining, minerals and geology! We were asked about the historic #NewCampbellton coal mine in #VictoriaCounty.
#nspoli #cbpoli #novascotia #capebreton #nshistory
@JaimeBattiste ImageImage
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. Image
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.

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 ImageImage
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 Image
...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. Image

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 ImageImage
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 ImageImage
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...
