Translations:AY Honors/Animal Tracking - Advanced/Answer Key/17/en
From Pathfinder Wiki
When the first cast of an animal track is made by pouring the casting material into the track, the result is a negative cast. It is called a negative cast, because rather than looking like the animal's track, it takes the shape of the animal's foot which made the track. A positive cast can be made by casting a negative track, and the result looks like the track left by the animal.
