The Wastelands of Anhur is a location on the planet Tagrea.
The Tagrean mathematics professor Tarek Solamon found many artifacts here. The wastelands also held the long-buried Stargate that was placed on the planet by the Goa'uld Heru'ur more than three centuries ago. Once Jonas Quinn and Teal'c found the Stargate, the Tagrean Commander Kalfas staged a military coup in the wastelands against Chairman Ashwan. Ultimately, Ashwan contained the coup. (SG1: "Memento")
