Boxhole is a young impact crater located approximately 180 km (265 km by road) north-east of Alice Springs in the Northern Territory, Australia.[1] 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,[2] placing it in the Holocene. The crater is exposed to the surface.[3]

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. A later search found additional meteoritic metal including an iron mass of 181 pounds (82 kg) ,[4] now in the Natural History Museum, London.
