The main material brought back was turquoise, but also other minerals (most of the Egyptian words in the text are not yet identified) and Petrified wood. There are several expeditions to the Sinai known, that date under Amenemhat II. For several reasons it seems most likely that the text refers to the one datable to year 29 of the king, providing a rough timeframe for the events mentioned on this fragment of the stone.[8]
