Can I find a photo of a landform created by tectonic shear in Canada?

    Canada Shear
AI Thread Summary
Reference material for tectonic shear landforms in Canada can be found on the Earth Science World website by searching under "Canada" and "tectonics." A notable example of a potential shear fault is located between Swanson and Crease Islands at the northern end of Vancouver Island. Additionally, a personal account describes the discovery of a fault line near Kingston, which was linked to fuel leaks and led to the demolition of nine houses. This investigation involved a geologist from the University of Waterloo and revealed interesting aerial observations, such as larger trees growing over the fault due to the proximity of bedrock. The fault was approximately 12 feet wide, filled with glacial till, and further excavation was attempted to explore its depth.

I'm looking for reference material. I need a good photo of a landform that is a direct result of tectonic shear. Canadian content strongly preferred - haven't been able to find any online.

Ooh thanks!
 
Google Earth: channel between Swanson and Crease Islands, N end of Vancouver Island, may be sitting on a shear fault.
 
fault line

I actualy dug up a faultline near Kingston a few years age. It ran just off the edge of a tank nest and was a conduit for fuel leaks. The resulting investigation led to me demolishing 9 houses. I have pics of the fault in the bedrock. I was tasked with trying to follow it a year or so later and made a video of the excavation process. We hired a geoligest from the University of Waterloo. His investigation led him to a Canadian geological survey seismology station a few miles from the site. It was monitoring the fault. His aerial survey showed a cool phenominon. The bedrock in this area is very close to surface, The trees in the fault were larger by degrees than the ones rooted in the very shallow soil. This was not a feature we could see from the ground but it was very clear from the air. Where I was working on it, the fault was about 12 feet wide, filled with glacial till and rock I could not tell the depth. I did end up putting a mini excavator down the crack to try to dig deeper. It was a fairly interesting job.
 
Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.
