The original concept involved the polar trips starting from accepted coastal points, involving long sledging journeys. Over time the significantly shorter, easier, and less serious "Last Degree" polar trips – from 89 degrees to the pole (at 90 degrees) – have been claimed as the Explorer's Grand Slam (
Last Degree). The climbing community, the
American Alpine Club,
The Explorers Club, climbing companies such as International Mountain Guides, define the Explorer's Grand Slam as having accomplished the Seven Summits plus (at a minimum – the last degree of) the North and South Poles. There is some consensus that a ''True Explorer's Grand Slam
means one will also have summited all 14 peaks above 8,000 metres (26,247 ft) (14 + 7 + 2). Likewise, there is some consensus that a True Adventurer's Grand Slam'' is achieved by also visiting the magnetic
north and
south poles. As of 2022, all terminology and guidelines regarding polar data records are being conducted under the Polar Expeditions Classification Scheme (PECS). In April 2005,
Park Young-seok became the first person to complete a ''True Explorer's Grand Slam'' (
