From Percé to Stonehammer

Good day, scientists!
We are very pleased to have a group of discussions where we will be able to study the science around us. Also, as the Geopark of Percé is hoping for a worldwide recognition of UNESCO (perhaps in 2018), we will discuss it together and see how it goes.
Our dear geologist, Agathe, began her great voyage of exploration of other geoparks in the world. She began her journey near us, at the UNESCO Stonehammer geopark, in the city of St. John, New Brunswick.
Let’s see what she found out!

Did you know that?
There are two geoparks that are already recognized by UNESCO in Canada.
The first is in New-Brunswick, in the south of the province, in St. John:
The second is in British Columbia, West of the country:

Agathe particularly liked the Geopark of Stonehammer because he was the first of North America to have been recognized by UNESCO. For a long time, the researchers have been in a position to find the first Canadian trilobites.
But what is a trilobite?
A Trilobite is a marine arthropode that has lived between 500 and 250 million years before today. To date, scientists have discovered more than 10 species of trilobite. The identification of these species gives very important information to scientists. If a specie and its ecology are known, its presence on a site allows us to understand better the environment that existed when the trilobite lived millions years ago!
Another fascinating element at this geopark is the famous Bay of Fundy. This bay is renowned for its giants tides. They can reach up to 21 meters! Their size is such important that high tides generate a local inversion of the current of the St. John River, near the estuary. So the river flows upside down! I hope fish have a good sense of direction!
Of course, there is much more to be observed at the UNESCO Stonehammer geopark, such as the trail of glaciers, volcanic rocks and shallow marine caves. For more information, visit
In the near future, Agathe will be headed for the second UNESCO geopark of Canada, in Tumbler Ridge, in the north of British Columbia.
Until then, I imagine you have at least one question about this great Geopark? I can’t wait to read it! I will choose and answer at least one question a week from the ones you asked me.
Enjoy it and let science stimulate your curiosity!
See you soon!
