Caves of Kaleemah
From The Stargate Omnipedia
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, but were subsequently destroyed by the blast wave of Anubis's mothership. Fortunately, the people were saved by Oma Desala, allowing them to ascend to the higher plane.
It should be noted that it is highly likely 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.
