Caves of Kaleemah
Hidden caves on Abydos where the people believed several of their population would be safe from Anubis's wrath. Kasuf himself took many women and children into this cave, which are believed to have been subsequently destroyed by the blast wave of an assault from Anubis's mothership. Fortunately, the people were saved by Oma Desala, allowing them to survive by ascending to the higher plane.
It is likely (though not confirmed) the Caves of Kaleemah are also the caves the Abydonian boys and the first Stargate team hid from Ra, as well as the location Daniel Jackson delivered Sha're's son, Shifu.
