Why these picks
We spend a lot of time looking at old mud and sand to see how water once moved. It is a bit like trying to read a book where half the pages are stuck together. Sometimes we need a different set of tools to see the full picture. This week we found some great stories about using magnets, sound, and even history to fill in the gaps.
These picks show us how the physical world keeps a record of everything that happens. You just have to know which tool to pick up. Does the ground ever feel like it is trying to tell you something? It is pretty amazing what you can find when you look past the surface.
