The point is one of the features named Pyritic or Esther Islands by Scottish geologist David Ferguson in 1913–14.
Although Ferguson represented the point as a rocky island separated from the ice cliff of King George Island by a channel 400 feet (120 m) wide, air photos show that there is no channel.
The word "gam" is an old sealers' and whalers' term for the occasions when groups of men from several vessels met in one of them for a gossip.
Nearby Esther Harbour was an anchorage frequently used by sealers.
