BIG boulder

[Ron Altier]

 This boulder fell on and blocked a highway here in Colorado. I didn't get the highway number, but it wasn't an interstate. They have no idea when or if it will be reopened. The only way to remove it is to blast it apart.

Ron that is huge! There could be a car under that an nobody would even know. I have a question, do you know what kind of rock that is? It's pretty dark in color, out here in So Cal we have a lot of granite, gray in color, but nothing that dark in color.

Sadly we have plenty of stuff in our arsenal to blow this up and move on.  The will and determination to do so is severely lacking.

i found the story.

Colorado is one of the western states known for its black granite. That would be my guss

[FlGatorwood]

While it is dark, it is not dark enough layered as coal.  My guess is that it is dark granite.  If you look at if from the road view, it has the holes like granite, but I am not a rock expert.  I'm just guessing.

On another note, a large coyote, carrying a box of dynamite, was observed running from the scene

Lew, that was a large land shark.

 The news this morning said that the boulder weighed approx 1.5 to 2.0 million pounds. I think they used a professional guesstimater They had one blasted into smaller pieces and was preparing to blast the other. It snowed again in the mountains and this season is one of the record snow winters up there. Now the serious part comes......a quick thaw and rain would be disastrous

From Wikipidea: In the construction industry, black rocks that share the hardness and strength of granitic rocks are known as black granite. In geological terms black granite might be gabbro, diabase, basalt, diorite, norite, or anorthosite.[1]

 

In my area, it might be dolomite, a magnesium limestone.

 But a "BIG rock!"

Too bad a rock quarry couldn't send out a crew and make use of it.

Like the Jeffersons, when they blast it, we can all get "A Piece Of The Rock"

I hope there's a video of that blasting...if they let anyone close enough.

It will take 5 years for all the government agencies to approve it.  You need watershed to deal with erosion, EPA for effects on environment of blasting rock into the air, then of course 3 years of oral dysentery in the courts over the rights of the boulder to remain a solid boulder.
