Environment
Lithology: not described
Taphonomic context: human accumulation, rock shelter
Archaeology: stone tools, other artifacts
Habitat comments: "Widgingarri Shelter 2 is 18 m long, 8 m deep and 1.5 m high at maximum above the present surface of the deposit".
Sediments were loose, sandy and rich in organic material to a depth of 30-35 cm, becoming redder in colour and more consolidated from Spit 4 onwards.
"Shells were concentrated in a lens in Spit 7 some 29-35 cm below the surface, decreasing rapidly below this".
"A total of 1769 stone artefacts were recovered from the excavation at Shelter 2", including points, flakes, etc.
