Knuckle Reef

Knuckle Reef ({{coord|67|50|S|67|22|W|source:GNIS|display=inline,title}}) is a reef lying off Beacon Head, Horseshoe Island, Antarctica. The reef was so named by the UK Antarctic Place-Names Committee in 1958 because the individual rocks in the reef, which are exposed at low tide, resemble the knuckles of a clenched fist.
