Ancient ground scars challenge early technology timelines.

In the gypsum flats of what is now southern New Mexico, time briefly stopped working the way it usually does. Footprints hardened, drag marks settled, and layers sealed everything in place. When researchers uncovered these tracks, dated to roughly twenty two thousand years ago, they expected a story about migration. Instead, they found something quieter and stranger. The marks suggest not just people walking, but people moving weight across a difficult landscape with intention, planning, and tools.
