For the Pitjantjatjara people living in the desert, knowledge of their water sources was critical to their survival.
This resulted in an intimate understanding of the landscape which continues today. Deep familiarity with the
topography of their country and the way rain would interact with the land ensured constant sources of water
could be found. 'Tjukula' means rock-holes, which are found with surprising frequency in the Musgrave ranges.
Between visits, Anangu (people) would use rocks and spinifex construction to guard these from spoilage by
animals and, particularly in more recent times, from feral and stock animals, cattle, camels, horses and
donkeys.
