Coolant + Brown Stuff

I took the cap off the coolant today to just check it. I noticed brown stuff floating around in there. Anyone ever see this or know what it is? No, I didn't crap in there either. It is only a year old. Guess I will have to have them flush it when it goes in for the yearly check.
