Yeah, wwh. Cranberries and their bogs are really fascinating.

But back to iron. I've been wondering. You see, out here on the farm the land is mostly red clay. And just today I was wondering what made the clay red. Do you think it's iron? I mean, iron turns red, doesn't it? So that's why I'm wondering whether there may be high iron content in the soil. When the rain works away at the clay, and the runoff moves into the dirt road, it turns into reddish-yellowish-orangish sand. But I'll bet there's high iron content in that clay.
