track

The impression left by an animal's foot in soil, mud, sand, snow, or dust — a single print that records the weight, gait, speed, and intention of the creature that made it. A track is not just a shape; it is an event frozen in substrate. The depth of the toe pads, the presence or absence of claw marks, the spacing between prints, the splay of the toes, the ridge of mud pushed up at the edges — all of it is information, readable by anyone who learns the language.
