We often tout #NovaScotia's amazing #geology but all four #Atlantic provinces have great geological sights - partly because we were all connected in supercontinent #Pangea 200-300 million years ago! We're going to talk about some spots in #NL, #NB and #PEI this weekend.

This is #AtlanticCanada 10,000 years ago. #PEI was still connected to the mainland - no #ConfederationBridge needed! Sea levels are lower during ice ages because so much water is frozen. It wasn't until 5000 years ago that rising sea levels made PEI an island.

#Newfoundland's #BellIsland had iron mines from 1895-1966. The #NovaScotia Steel and Coal Co. helped open the first one. The iron was made into steel in #Sydney, #CapeBreton. Steel is iron and carbon (which is derived from coal) so #CB coal and #NL iron were a good match!

Rocks may all seem pretty hard but some are harder than others. #Sandstone is a softer rock which is often eroded by the sea. That's how #PEI's #TeapotRock formed. The sandstone around it eroded leaving just a sea stack - a rock column with this great shape.

#NS shares the #BayofFundy with #NewBrunswick. NB's #HopewellRocks are eroded sandstone, a soft rock easily eroded by Fundy's powerful waters. Enjoy them while you can: it might take 1000s of years but these sea stacks will collapse 1 day! The good news is more will form.
