This large silcrete flake is from a quarry in southwest Queensland.  A siret arris can be seen on the dorsal surface of the flake.  It was collected during a collaborative research project between archaeologists and Traditional Owners to better understand the deep history of the Mithaka People.

This large flake was stuck by hard-hammer percussion at a silcrete quarry.  The blow that detached this flake was aligned directly behind a prior scar on the core face.  This approach was sometimes used at this quarry to produce macroblades with a trapezoidal cross-section.  The prior scar on the core face—now the dorsal scar on this flake—is marked by a prominent siret arris.  This feature is created on the face of a core when the flake splits lengthwise by a bending fracture during detachment.  Refer to the annotations for the model, and this discussion, for more details on the mechanics of siret fracture.

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.
