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.
