In the Baraboo Hills of Wisconsin, 1.7-billion-year-old quartzite formations hold water patterns frozen in stone—just as if waves had left their mark in the sand yesterday. Tidal memory reveals the vast expanse of time condensed into something we can touch, something our human minds can grasp. When I place my hand on this ancient rock, I am touching an object formed when the first multicellular organisms came into existence. This is a deeply relational experience, a way of sharing common ground with ancient life across deep time. And just as this rock carries the past, it also holds the future—life yet to unfold on this shared stage.
