Why these picks
Pull up a chair and grab a drink. You know how we spend our time looking at mud and dirt to figure out where ancient rivers used to flow? It turns out we aren't the only ones playing detective with the planet. Some people use light to see when a grain of sand was last above ground, while others use fine dust to find hidden patterns in stone.
It is all about finding those tiny clues that stay hidden from the naked eye. Whether it is a glow from a mineral or the ring in a piece of old wood, these stories show how much we can learn if we just know where to look. I picked these because they remind me that the past isn't gone; it is just waiting for us to find it. Ready to see what I mean?
