Waves, sand, rocks and Arctic Plants, Neys Provincial Park, Ontario, Canada

Waves, sand, rock, and flora, Neys Provincial Park, Ontario, Canada. Season 22, episode 4 In this Rambles With Robin and Ruby video, I describe some simple geological features and two Arctic disjunct flower species, all seen within Neys Provincial Park, Ontario, Canada. We look at the way waves impact a sand beach on the beach face, beach berm, and back shore along the shore of Lake Superior. We then look at two Precambrian rock types, that are 1 billion years old, related to the Coldwell Complex: syenite and gabbro. Those two rock types are cut by younger diabase dikes. The billion-year-old Precambrian syenite and gabbro rocks were shaped by an ice sheet during the last ice age, which ended about 15,000 years ago. We look at some glacial features preserved in the old rock. Finally, we look at two Arctic disjunct flora species, which are common on the rocky shore of Neys Provincial Park: Common Butterwort (Pinguicula vulgaris) and Mistassini Primrose (Primula mistassinica). Their presence is sustained by the Arctic-like conditions that are maintained by the large body of cold Lake Superior water. The common butterwort (Pinguicula vulgaris) is interesting because it is a carnivorous plant that gets some it its nutrients from insects that it traps on its sticky leaves. Cartoons by E. Ginn.
