On November 29, 1954, Norweigan freighter SS Lionne ran into the #CansoCauseway. It didn’t open until the following year and it was not yet on British Admiralty navigation charts.

The Lionne's crew didn’t know we were in the process of connecting #CapeBreton to mainland #NovaScotia.
Rock aggregate for the construction was quarried at Cape Porcupine, right next to the causeway.

It took 10 million tons to build because it's 24 metres wide at the top, 192 metres wide at bottom, and 65m deep in some spots. They thought there might not be enough rock to build the Causeway but the quarry is still going strong 7 decades later!

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

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.
