"Carbon Creek" is the second episode of the second season of the science fiction television series Star Trek: Enterprise, the 28th episode overall. It first aired on September 25, 2002, on the UPN in the United States. Only three of the main cast appear in this episode. It features a flashback story, and T'Pol tells how first contact between humans and Vulcans actually happened far earlier than the date officially celebrated. Three Vulcans, including her great-grandmother T'Mir, also played by Jolene Blalock, crash landed on Earth in 1957 shortly after the launch of Sputnik. It was directed by James A. Contner, his second episode of Enterprise as director. It was filmed partly on location in Crestline, California.
