Windjana Gorge Water Tank Shelter (DIA 12588) is a narrow limestone rockshelter located in Windjana Gorge National Park, Western Australia. Although the site is badly disturbed, test excavation revealed some 45cm of in situ deposit down to massive roof-fall. Radiocarbon estimates demonstrate that the shelter was used from at least 7000 calBP into the European contact period. The sediments contain well-preserved faunal remains and stone artefacts. The faunal remains give an insight into Aboriginal economy in an arid region with adjacent fresh water sources.
