Notes A rockshelter located in in Mikinj Valley, southwest Arnhem Land. The rockshelter was an elevated terrace some 13 x 7 m in size, and overlooks Birriwilk lagoon. The rockshelter contains 30 images of primarily bi and tri chrome x-ray fish art, as well as few animals. Excavations consisted of 1 sq. m at the base of the rock art panel within the shelter. Excavations reached bedrock at 103 cm below surface. Excavations recovered 412 artefacts, charcoal, shell and worked and unworked ochre. Glass was also found in XU3-4. Data suggests initial use from XU 31 at c. 4.5ka (Wk-33541) with intermittent use from c. 4ka (Wk-32919) and peak activity between c. 0.7-0.3ka (Wk-33540-Wk-33542), with decline in use in uppermost deposits. Artefacts show changing use in material over time beginning with tuff, then chert and finally quartzite, the latter being associated with bifacial points. Faunal remains included turtle and fish species.
