It is expressed as a rimless circular flat-floored depression, 1.2 kilometres (0.75 mi) in diameter, within mountainous and heavily forested terrain 26 kilometres (16 mi) south of Queenstown. It lies east of the West Coast Range and the former North Mount Lyell Railway formation, and just within the Franklin-Gordon Wild Rivers National Park.
The crater was discovered by the geologist R. J. Ford in 1972, after a search for the source of Darwin glass, an impact glass found over more than 400 square kilometres (150 sq mi) of southwestern Tasmania. Geophysical investigations and drilling have shown that the crater is filled with up to 230 metres (750 ft) of breccia capped by Pleistocene lake sediments. Although definitive proof of an impact origin of the crater is lacking, the impact hypothesis is strongly supported by the relationship of the glass to the crater, as well as the stratigraphy and deformation of the crater-filling material.
