Piccaninny crater
Template:Short description Template:Use Australian English Template:Infobox terrestrial impact site
Piccaninny crater is an impact structure, the eroded remnant of a former impact crater, situated in northern Western Australia in the Kimberley region. It was named after Piccaninny Creek and lies within the Purnululu (Bungle Bungle) National Park.<ref>Template:Cite Earth Impact DB</ref>
Description
The site is marked by a circular topographic feature on top of the flat-topped sandstone and conglomerate Bungle Bungle Range, clearly visible on remotely sensed images.<ref>https://maps.google.com/maps?q=Australia&ie=UTF8&om=1&z=12&ll=-17.421408,128.444939&spn=0.128409,0.342636&t=k Google Maps image</ref> When first reported in 1983 after aerial observation, it was interpreted as either an impact structure or a cryptovolcanic feature.<ref name="b83">Template:Cite journal GSWA download search Template:Webarchive

The circular topographic feature is 7 km in diameter, although due to the amount of erosion the original crater may have been larger. It has been estimated that the present land surface is 1–2 km below the original crater floor.<ref name="ss85"/> The impact event has not been dated, and must be younger than the Devonian age of the rocks in the area, but is clearly not recent because of the amount of erosion.
