Named by the United States Advisory Committee on Antarctic Names (US-ACAN) (1997) after James B. McClintock, Associate Professor of Biology, University of Alabama, Birmingham, who studied the benthos of McMurdo Sound west of Ross Island and along the coast from Granite Harbor to Cape Chocolate, including extensive work in New Harbor in proximity to this point.

Named by US-ACAN after Baldo Marinovic, graduate student (biology), University of California, Santa Cruz, and member of the 1985 winter party at McMurdo Station.

During 1984-85, the sea off this beach was a site for the study of reproductive biology and larval ecology of shallow-water echinoderms by biologists of the University of California, Santa Cruz.

Named by US-ACAN (1997) after Bill James Baker, Associate Professor of Chemistry, Florida Institute of Technology, Melbourne, FL, who conducted underwater research in several areas of McMurdo Sound during the 1992-93, 1993-94 and 1996-97 field seasons, including work at Cape Evans, Razorback Islands, Hutton Cliffs, Arrival Heights, and New Harbor, the location of this point.

Named by US-ACAN (2000) after Allan T. Weatherwax, physicist, Institute of Physical Science and Technology, University of Maryland, who conducted investigations of the atmosphere, ionosphere, and magnetosphere at McMurdo Station, South Pole Station, and several of the Automated Geophysical Observatories (AGOs) located on the Antarctic plateau; completed 10 field seasons in Antarctica, 1988-89 through 1998-99.

So named by them because the Ferrar Glacier party left a tin of butter here, in anticipation of obtaining fresh seal meat at this point on the return journey.
