GREENLAND is one of the world's last uncharted wildernesses but former Brockenhurst College student Jon Roberts aims to fill in some gaps on the map.

Jon, 25, who first learned to scale sheer rock faces as a member of the college climbing club seven years ago, is to lead a small team on an expedition to southern Greenland next month.

As well as tackling jaw-breaking place names like Aappilattoq and Agdlerussakasit and enduring potentially tent-ripping storms, the team plans to conquer one of the tallest sea cliffs on earth.

They are heading for the Cape Farewell area - one of the few landmarks in Greenland with a pronounceable name - and will chart a new route up the east face of "The Thumbnail," or Pamiagdluk, hoping that the world's rock-climbing fraternity will rise to their challenge.

"Rock climbing has its fashions just like anything else, and Greenland has been a forgotten country since the 1960s," said Jon at home in Ashurst in the New Forest.

"Our expedition could help make Greenland's mountains and cliffs as fashionable as the Himalayas. So many places have been overdone. Greenland is almost totally unexplored. Nearly every place name is in the Inuit language, and the middle of the map is just a big white space."

The Mount Everest Foundation and the British Mountaineering Council are supporting Jon's month-long trek for the benefit of international geography, but Jon hopes there will be another beneficiary - international aid organisation UNICEF.
