Hammerston was a town located in Louisiana.

In 1957, the Sixth Doctor and Mel investigated UFO sightings in the proximity of Hammerston and became involved in the production of the film Swamp of Horrors after attacking an actor in a rubber alien suit whom they mistook for a genuine alien. The Doctor, who used his pseudonym "Dr. John Smith", and Mel were assumed to be uncredited actors playing fictional characters by film critics. (PROSESwamp of Horrors (1957) - Viewing Notes)
