How many times do
you pick up a rock and ask what it was made of? Do you ever want to
know where that bunch of rocks sticking up in the middle of nowhere
came from; why some mud is muddier than others; how the mountains were
formed; was the earth really once covered with water?
This part of the
Montana Bureau of Mines and Geology's site addresses some of the questions
that inquisitive minds want to know.
