Why these picks
We spend a lot of time thinking about what’s deep under the sand. But seeing the invisible isn't just for finding old riverbeds. This week, I found some great reads from friends who are looking at the ground from different angles. One group is making sure city streets don't collapse. Another is looking at how nature’s own anchors—tree roots—keep everything together better than any man-made wall.
It’s all about the same core idea: the surface doesn't tell the whole story. Whether you use radar or just look at how dust settles on a rock, you’re reading a hidden history. Isn't it wild how much we miss just because we can't see through dirt? These stories show that the methods we use to find water are being used in some pretty surprising ways elsewhere.
