phosphate

I've been curious about Phosphate lately. This "thingy" pictured here is a Dragline. It digs out big scoops of dirt and rock. It walks. It is used to mine phosphate. It's pretty impressively huge.

So, why am i ruminating on phosphate mining? No idea. I had these neat pictures from when we toured the mine and i had no idea what phosphate was or why. So i looked it up. click the links if you are interested. or not.
