The Egyptians knew that ships journeying to Punt would have to be carried across the Eastern Desert and re-assembled on the Red Sea. A number of dedicated anchors have been found at Sawwu or Ras el Gawasus on the Red Sea as part of a Middle Kingdom expedition to Punt. Routes across the desert also intersected areas of valuable quarry stone and gold. Soldiers/workers protecting the ships travelling to Punt would also be put to work mining and quarrying in the Eastern Desert. Numerous inscriptions in the Eastern Desert attest to their captains' names and ships' names. The Turin Papyrus represents a unique "geological" map of the Eastern Desert routes and places.
