tracing float
A process in which float is followed back to its origin. A prospector moves up slope looking for pieces of float until no more are to be seen. If, at this point, no outcrop is visible, the probabilities are that soil or loose surface material covers a hidden outcrop, which can be sought by digging pits or trenches.
