We love our coasts - especially in this heat! - but don't often think about how they came to be. Here's how #Halifax's #NorthwestArm formed:

Much of peninsular #Halifax’s bedrock is slate. Sediments deposited as deep-sea muds 500 million years ago were compacted into shale 450 million years ago. When North America and North Africa collided 400 million years ago as a result of tectonic plate movement...

...the heat and pressure generated by the collision turned the shale into slate. That’s how slate is formed – it’s metamorphosed (transformed) shale.
The #NorthwestArm was formed by glaciers eroding the slate and carving a trough in the bedrock.

We love getting questions about mining, minerals and geology! We were asked about #PointPleasantPark so here are some of our favourite spots in the park that we look forward to visiting when things get back to normal (stay safe in the meantime!).

The Golden Gates at the entrance to #PointPleasantPark are actually iron painted #gold. They were made in 1886 by #Dartmouth's Starr Manufacturing. Starr was best known for its innovative ice skates - even the King of Spain owned a pair. His had real gold plating though!

The Quarry Pond was a quarry in the late 1700s and 1800s, one of over 50 in #PointPleasantPark that helped build its forts, roads and walls. It later filled with water and became the pond we know today.
