Since potholes are generally considered to have been formed by erosion over long ages of time, the rocks in which they occur would also seem to be of great age. Some geologic interpretations account for these topmost rocks as deposits formed during the Biblical flood. The presence of potholes poses a problem for these interpretations. The details of the uniformitarian theory of the formation of potholes are examined, and contrasted with the well-known characteristics of potholes. It is evident that the uniformitarian theory of pothole erosion falls short of accounting for the phenomenon of potholes in many ways. Potholes therefore cannot be regarded as evidence for a great age of the rocks in which they occur.
