Thread: That's a big boulder

Years ago they built a bypass around the town of Kenora so you did not have to go through it while on the TC Hwy. There are rock cuts all along the TC Hwy in North Western Ontario so these rock slides do happen but I have never seen a boulder this big on the road here. It's something I might expect in the Rockies. If your timing was bad it could really ruin your day.

You know, in Norway many of the smaller cities are located at the ends of fiords. Sometimes they have massive landslides which cause tidal waves that take out entire towns killing everything in it's path. They try and monitor bad areas and have warning systems giving them a few minutes to evacuate.

Here in New Mexico in the Taos Canyon it is known for rock slides that have routinely taken out cars and buses. They finally installed steel cable fencing lining all the unstable areas which has eliminated the problem. Being swept into the Rio Grande Rapids is no fun.

Even the small ones would ruin your day.

Yep. That's a big boulder all right. That thing would flatten your car like a beer can with you in it.

This is not in any fjord or a canyon but on a road that runs through a boreal forest making this a very unusual occurrence for a boulder this size to fall on the main east/west highway across Canada.

I was only referencing what a big rock or rockfall is capable of.

Forest or not that rock had to come from somewhere.

Yea, the boreal forest is on the Canadian Shield which is rock. It comes from a rock cut that they make in the shield to run a road not some high mountain or from the top of a big canyon. Yea, the Franks Slide, where a mountain face came down due to mining was the last time I saw a boulder that size in the debris field.

Looks like a blasting engineering oops. They will have to make it smaller to move it that’s for sure.

Yea, hope they don't use the same blasting engineer to make it smaller.

We had one in Boulder Canyon about that size. It was planned blasting that brought it down, but it brought down about 10X what they were trying for.

Edit; I just read the article. It was 20X the amount of debris of an average blast.
