#SydneyMines played a key role in #NovaScotia’s coal mining and industrial history.
Here's the story...

#SydneyMines was named after Thomas Townshend (1733-1800), First Viscount Sydney, who was British Home Secretary in the Pitt Government in the 1780s. He was an important player in negotiating the Canada-US border.

He felt the British needed to keep Canada so loyalists – Americans who supported the British side in the US War of Independence - would have a safe haven to go to after the war.

We love getting questions about mining, minerals and geology! We were asked why volcanoes often form along tectonic plate boundaries:
The Earth’s surface is made up of a dozen large tectonic plates and a number of smaller ones.

These plates move imperceptibly - a few centimetres per year - and over the course of millions of years continents and oceans move and change shape. The plates pulling apart cause fractures or deep rifts in the Earth’s crust, both on land and under the sea...

...and plates colliding with each other form mountain ranges and new islands as the rock is forced upwards. It’s this powerful tectonic activity that results in so many volcanoes at plate boundaries.

The Louisbourg Lighthouse, by the Fortress of #Louisbourg in Cape Breton, was the first built in #Canada.
Check out this thread for its history!

#Louisbourg lighthouse was built by the French in 1734 of fieldstone, also known as rubble stone - rough, unhewn rocks set in mortar, but not laid in regular courses. The lighthouse had a slate roof.

While the tower was made of stone, the frame for the lantern was made of wood and it caught fire and was destroyed in 1736. A new lantern was built and finished in 1738. It was designed to be fireproof – it had 6 pillars of cut stone which supported a brick roof.

We love getting questions about #mining, #minerals and #geology! We were recently asked about historical mining in #PortHood, #Inverness County. Here’s our answer:

#nspoli #cbpoli #NovaScotia #CapeBreton #NS #CB ImageImage
In the 1740s-1750s, a quarry on #PortHood Island was the main supply of finished/dressed sandstone for #FortressLouisbourg’s window and door casements. About 60 men worked there in summer and the stone was sent by barge through the #StraitofCanso to #Louisbourg.

Many historical #NovaScotia buildings, including the more important buildings at #Louisbourg, were made of stone that was considered somewhat unattractive (i.e. fieldstone or ironstone), so it was often fancied up with granite or sandstone trim.
