Geography comments: "Puritjarra is situated in the Cleland Hills, 60 km west of the MacDonnell Ranges on the northern rim of the Amadeus basin" in central Australia.
Deposition of the fossiliferous Layer 1 began 8.3 ka with the earliest remains dating to less than 0.7 ka (dates for the underlying Layer II are uncalibrated, so these are also presumed to be such)

Environment
Lithology: sandstone
Taphonomic context: human accumulation,rock shelter
Archaeology: hearths,stone tools,other structures
Habitat comments: "Layer 1 is a consolidated layer of sand and rock spall ... grading into aeolian sediments outside the rock shelter".
"The matrix of Layer 1 is made up of light-brown sand, sandstone rubble and numerous fine rock fragments".
"The layer contains lenses of rockfall, intact hearths and pits, well-distributed pieces of charcoal and finely fragmented bone". Numerous flaked stone artefacts are also present.
