Geology of Eastern Canada and the Eastern United States
October 6th (Tuesday), 6 p.m., via Zoom (online) – Open to Public. Presentation: “Geology of Eastern Canada and the Eastern United States”; Presented by Mike Adler, Geologists of Jackson Hole.
This talk will be about the shared formation and geology of eastern Canada and the United States, which will be illustrated by pictures from the speaker’s 20 plus trips by sailboat and kayak to northeast Canada. The talk will begin with a discussion of the geology and formation of northeast Canada and the US focusing on the period starting in the Ordovician(475MYA) when the Iapetus ocean collapsed and there was a collision of the North American, European, and eventually African plates – which were then all part of the last “super continent” of Pangea. The result of this plate-plate collision was the formation of the Laurentian and Appalachian mountains in North American and the Caledonian mountains in Europe. Later when the Atlantic Ocean began to form as these plates subsequently rifted apart, there was an exchange of land masses that left parts of Africa in North American and left a piece of Canada to form present day Scotland as part of Europe. Pictures of the geology and scenery will be shown including a first ascent of the highest mountain in Canada east of the Rockies. This area in northern Labrador features some of the oldest rock in the world dating from 4.2 billion years ago.
