This large silcrete flake is from a quarry in southwest Queensland.  It was collected during a collaborative research project between archaeologists and Traditional Owners to better understand the deep history of the Mithaka People.

Artefact on loan to Archaeology and Palaeoanthropology, University New England, catalogue name Brokehimarm Lower, Area D, Collection No. 3.

See the annotations for technological details about this stone tool.

This large silcrete flake from a silcrete quarry was detached by a a very strong hard-hammer  blow onto the platform edge.  This caused the dorsal surface of the platform to shear off from a wedging-initiated crack.  Prominent undulations are present on the ventral surface, indicating an unstable crack as a result of the strong blow.  The ventral surface is marked by an unusually deep eraillure scar.  Evidence for forceful blows to detach large flakes are common at quarry sites, as are pieces of shatter caused by these high-impact blows.  Another example of this, from the same quarry, can be viewed here.

Brokehimarm Cave is located near Moondah Lake at an elevation of around 80 metres. The site complex has a number of silcrete outcrops on the top of the low relief escarpment, but this artefact was found in an extensive scatter approximately 100 metres long and 20 metres wide immediately below the cave. The material looks very similar to the material in the outcrops above the cave site. There are a number of other features in the landscape nearby including a large stone arrangement, possible initiation circles, knapping floors, earth ovens, and potential gunyah (hut) remains.
