(A) Field photograph of exceptional shatter cones near the center of the structure. Photo credit: A.R.B./Harvard University. (B) Geologic map of the structure, which occupies the north flank of North Pole Dome. Red points indicate shatter cone outcrops, which occur within an ~6.47-km–diameter area (blue solid circle) centered on the inferred point of impact (blue square). An inferred total diameter of ~16.2 km for the structure (blue dashed circle) is calculated from scaling laws using the shatter cone occurrence diameter (37). The map data are modified from the GSWA (83) based on our mapping. (C) Context map showing the location within Australia and the Pilbara Craton. -- Science Advances via PubMed
