Boxhole crater

Template:Short description Template:Use Australian English Template:Infobox terrestrial impact site Boxhole is a young impact crater located approximately 180 km (265 km by road) north-east of Alice Springs in the Northern Territory, Australia.<ref>Template:Cite book</ref> It is 170 metres in diameter and its age is estimated to be 5,400 ± 1,500 years based on the cosmogenic ¹⁴C terrestrial age of the meteorite,<ref>Kohman T.

Description

In 1937 Joe Webb, a shearer at Boxhole sheep station, took geologist Cecil Madigan to examine the crater. Madigan discovered nickel-bearing metallic fragments and iron shale-balls similar to those found at Henbury to the south of Alice Springs.<ref>Madigan, C. T., The Boxhole crater and the Huckitta meteorite (central Australia). Royal Society South Australia Transactions and Proceedings, v. 61, pp.187–190. 1937</ref> It was the second impact crater to be described in Australia, after Henbury.<ref>Haines P.W. (2005).
