The Stewart expedition found a small pyramid temple, several miles outside of present-day Cairo, Egypt. They uncovered several artifacts, including 10,000-year-old canopic jars into which Osiris and Isis had been banished. The ship transporting these artifacts to the United States sank off the coast of New Jersey six months after they were discovered. Isis died when her canopic jar was damaged in the shipwreck, but Osiris's jar remained intact. (SG1: "The Curse")
When the Stewart expedition members unsealed the tomb, they were exposed to mold spores that caused them all to die within a year. (SG1: "The Curse")
