Look, they welomed, ME, personally!!! The copper mine has been around since the 1800's.
You can see Kennacott from space. Isn't that mind-blowing?
Ok, I must admit, I didn't realize that Kennacott was an "open" mine. Since I lived in Price, Utah growing up, I assumed all mining was done undergrown! Kennacott is 2.5 miles across at the top and .75 miles deep, and going deeper.
If you stretched out all the roads in the open pit mine, you'd have 500 miles of roadway - enough to reach from Salt Lake City to Denver.
Humongous trucks, 255 to 360 ton, haul the ore out of the mine. If you look closely it the picture above, you can see the huge trucks, being followed by a "normal" vehicle. Each wheel on the mammoth trucks cost $18,000-26,000 and only last 9 months. Below is a picture of one of the tires with a 4th grader standing beside it.
I must admit, I had a great time, but the kiddos were bored. I asked them if they would have rather been back at school doing work and they all resonded, "YES." Go figure!!!
