The wooden boardwalk from the Coastal Discovery Centre at Main á Dieu on the southeast coast of Cape Breton Island, in Nova Scotia, Canada, leads to a look-out platform that is built on top of a rocky outcrop. The rock is a basalt volcanic lava flow dating from the Neoproterozoic Period around 560 million years ago. The basalt is characterised by many interesting natural fracture patterns; veins and weathered surfaces of contrasting colours; and different textures depending on exposure to aerial or aquatic erosional elements.
