Lhotse South Face, Solo Winter Attempts. There were two separate unsuccessful attempts made by Frenchmen to climb the south face of Lhotse in winter. On November 29, Marc Batard reached 7000 meters before giving up. Accompanied by Catalán Enric Lucas, Christophe Profit reached 6700 meters on December 18, but after two bivouacs there, the pair had to descend in bad weather. Lucas then returned to Spain. Profit made a solo attempt on January 13 and 14, 1990, which reached 7150 meters, where his tent was destroyed by the wind. A final attempt from January 19 and 21, 1990 failed at 7600 meters.
