When I was in grade six, my teacher told the class that the Copper Mountain got its rocky steep cliff from the glaciers about 10,000 years ago. As the ice moved down the Skeena Valley, it carved the steep cliff we see today, Well he was wrong according to the latest research that I have seen. In fact, the face of the Copper Mountain is the result of fault lines that run along each side of the valley. Picture the valley floor being pushed down and the mountains being pushed upwards. (Geo Tour 2007-10, 4) Yes I source my Blog Posts. SO, what we are seeing, is the Fault that exposes the mountain, and the valley floor, from when the ICE age took place. Not like the story I heard from the local Theologian, who said “Copper Mountain is the result of when God sneezed and blew a Loogie (sic) in the North Coast, that became the Copper Mountain. Not quite. But in all honestly, this mount always gives a sense of awe a wonderment what looking at the rock formations while in Upper Thornhill, BC. by the Golf Course.
Yes, today id the long weekend, May, 20, 2019. The unofficial start to summer, and it is like summer indeed.
OK, back to Copper Mountain. Looking at the cliffs, you see many rock formations, and the way the granite rock fractures when it was trusted upwards. See my images.
The granite Volcanic rock is between 200 and 60 million years old (GeoTour 2007-10, 9). and was sea floor, which explains why you can find seas-fossils in the rocks at the North end of the Mountain. When I get a access to a truck, I may drive out to the fossil beds and photograph a 60 million year old sea shell.
Another tid bit of information about the Skeena Valley. And I found these as kid in my back yard at my parents house, are limestone fossils. Somewhere I have a chunk of limestone with sea shells in it. According to this paper, the fissiles are over 270 million years old (Geo-tour 2007-10, 7). These are some of the oldest fossils in the world, and they predate the dinosaur. What is even more weird, is that they formed while this part of the content was down around the Mexico area!
OK, here is the linke to the paper I read.
