In cartography, the blank spaces on maps are called sleeping beauties. Antarctica has many of them, so many that it is common practice to name everything you come across as an expeditionary exercise of discovery that, perhaps, will transcend time.
These blank spaces are traced on the maps with rectangular figures and the inscription ‘No Survey’ next to the spaces already delimited. These Sleeping Beauties preserve the pattern of use of geographical charts, but this time on photographs of landscapes typical of this territory.
