Antarctica, Overview. The 1999-2000 season was the busiest season ever for tourism in Antarctica. This popularity was reflected in the relatively high number of mountaineers active on the continent, particularly in the Peninsula area. Most yacht-based climbers reported generally good weather, and in the Sentinel Range the extremely poor weather of the previous season did not materialize, heralding a return to the traditionally high success rates on Vinson Massif and Mt. Shinn.
