So named by the northern party of NZFMCAE, 1962-63, because they established their most northerly survey station here on the turning point of their traverse.

A cluster of closely spaced nunataks rising to 2,300 metres (7,500 ft) high, centered 3 nautical miles (5.6 km; 3.5 mi) east of the south end of Neall Massif.

Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) in 1983 after J.B. Jago, geologist with NZARP geological parties to this area in 1974-75 and 1980-81.
