A Geosites Adventure in Newfoundland
On the beautiful morning of August 17, IAT/IATNL Chairperson Paul Wylezol and IATNL Finance Director Kevin Noseworthy set off in a dory from Cox’s Cove, Bay of Islands with Darren Park of Four Seasons Tours in search of Middle Arm geosites for the IATNL planned Cabox Global Geopark.
The Geopark will feature 3 basic zones of the Humber Arm Allochthon: the Ancient Continental Shelf of North America, the Transported Continental Margin of North America, and the Bay of Islands Complex Ophiolite Massifs.
The tour’s first stop was Middle Arm Point between Humber Arm and Middle Arm. Its exposed and weather-beaten headland is a good example of the Zone 2 Cook’s Brook Formation.
There you can see layers of sedimentary limestone and sandstone folded in unique patterns when tectonic collisions closed the Iapetus Ocean and formed the Appalachian Mountains more than 250 million years ago.
From Middle Arm Point, the trio turned back and headed east into Goose Arm and the rising sun. For more on the story, go to the IATNL website.
