Since the beginning of the fall semester 2010, I am pleased to take my classes on Monday with Environmental Geology at UQAM. As you know, that I have to go drool over (see here) but now that we have to make more field trips! Poor me ... Seriously, it was really very interesting geology applied to the environment around us. We started our journey in the Falls Park Rawdon (which is a very beautiful village by the way) to see Gneiss Metamorphic Canadian Shield (the Canadian Shield, the top of its 2.4 billion year of existence, is part of the oldest rocks found on the Earth!) and then we continued up to the Laurentians for the time scale and Attractions:
- limestone group Black River filled with fossils from the Middle Ordovician (-450 million years) in Fisk Mill Crabtree;
- old sandstone 500 million years at Saint-Liguori;
- stigma left by the glacier and till cooler left by the last ice age 20,000 years ago, and
- sands witnessed the coast of the Champlain Sea that existed here between 14,000 and 12,000 years.
short, it was very beautiful, very interesting and in addition, part of every stop was great and the day was perfect to enjoy a flamboyant Canadian autumn:
Ouareau River at Fisk Mill
St. Liguori
Falls Park Magna Rawdon
Rawdon again ...
... Rawdon and always!
No, I did not take pictures of that tree, I also took pictures of stones and rocks, but I'll spare you that ...
Finally, it is not that bad studies in geology!
