Greenland Icecap, South to North Unassisted Crossing. It was reported that on June 13, Norwegians Rune Gjeldnes and Torry Larsen, who had made the 540-mile west to east traverse in 1994, became the first to traverse Greenland south to north, a 1,645-mile journey. The duo made their traverse in 93 days on skis, with sleds and kayaks and ski sails, and with no outside support. It was the longest unsupported polar expedition ever completed. (Rock and Ice 75)
