Stargate SG-1 - Season 2, Episode 14 - "Touchstone"

SG-1 visits a planet where the indigenous people have the ability to call forth whatever type of weather is needed to sustain their crops and their way of life by using a powerful device called the touchstone. After a de-briefing at the SGC, General Hammond authorizes SG-1 to return to the planet to further study the touchstone but find that it has been stolen. Witnesses on the planet accuse SG-1 of the theft, claiming that the perps were dressed in SGC uniforms. An investigation leads to the discovery of an unknowngovernment organization using the second gate to steal technology. SG-1 tracks down the second gate in Southern Utah. (my home state!) They are able to retrieve the touchstone, but the identities of the men who are using the second gate still remains unknown. The second Stargate has a permanent iris welded to it and is now being kept under lock and key at the SGC.
