from the center of the Earth than is the peak of Mount Everest. The summit of Mount Everest is 2,168 m (7,113 ft) closer at 6,382.3 km (3,965.8 mi) to the Earth's center. Peru 's Huascarán contends closely with Chimborazo, the difference in the mountains' heights being 23 m (75 ft) [ citation needed ] The lowest point underground is more than 2,000 metres (6,600 ft) under surface. For example the altitude difference in the Voronya Cave between the entrance and the deepest explored point (its depth) is 2,191 ± 20 metres (7,188 ± 66 ft). In 2012, Ukrainian cave diver Gennadiy Samokhin has reached the lowest point, breaking the world record. [ 4 ] The point closest to the Earth's centre (~6,353 km (3,948 mi)) is probably at the bottom of the Arctic Ocean (greatest depth 5,450 m (17,881 ft)) near the Geographic North Pole (the bottom of the Mariana Trench is near 6,370 km (3,958 mi) from the centre of the Earth). Road (mountain pass): Mana Pass on the India - Tibet border contains a well-graded military road built in the 2005-2010 period that reaches 5,610 metres (18,406 ft) 250m west of the low point of the pass at 5,545 metres (18,192 ft). Semo La in Tibet 5,565 m (18,258 ft) or Marsimik La in India, 5,582 m (18,314 ft), are other contenders, depending on the definition of "attainable by transportation". There may be higher motorable passes in Tibet in areas affected by lack of information and restricted
