The mine is 2 3/4 miles across and 3/4 of a mile deep. It is very hard to get a picture that shows how massive it is. We were all very impressed. We spent some time wandering around the platform that overlooks the pit, and when we were hot we went inside the Visitor's Center to look at displays and watch a short movie. I was worried my kids would get bored because this was a "learning" activity, but they really enjoyed reading the different displays.
What impressed them the most is how everything is SO BIG! This hauler is huge! Notice the stair case along the front. To get an idea of HOW BIG these trucks are......
And to give you an idea how big the pit is.....
