Kazimierz Olech was born in
Kraśnik, Poland in 1928
. In his youth, he participated in Scouts and played
volleyball for his school team. Kazimierz Olech first went to the
High Tatras in 1947, and began mountaineering in 1954. He went on to climb hundreds of routes across the Tatras. In 1957, he set out to climb the entire ridge of the Tatras, from
Huty at the western end to
Ždiar in the east. It took three attempts and the loss of a climbing partner, Ryszard Wawra, before successfully making the first winter ascent of the
Tatra ridge with
Andrzej Zawada in 1959. In 1957, he began climbing further afield, heading to summit difficult routes in
the Alps, the
Caucasus, the
Hindu Kush, and the
Pamir Mountains. He made a number of first ascents of unclimbed six- and seven-thousanders, including: Kohe Tez (7015 m) in 1962, Kohe Farzand (6185 m),
Lunkho e Dosare (6901 m) and Kohe Urgent (7038 m) in 1968. In addition to mountaineering, he was a
spelunker. In 1966, he spent 14 days underground mapping passages of Szczelina Chochołowska, the largest cave in the Chochołowska Valley in the Western
Tatras. In 1978, he summited the then unclimbed central route of
Kangchenjunga (8482 m, setting another Polish altitude record). The leader of the expedition to Kangchenjunga, Piotr Mlotecki was banned from climbing in Nepal for 5 years after the central summit, as the expedition did not receive official permission to climb these routes in advance. , Kazimierz Olech and
Andrzej Czok at Mount Everest base camp (1980) In 1979 and 1980, Olech participated in summer and winter expeditions to
Mount Everest. After the summer expedition, Olech remained in base camp until the winter expedition arrived. He would spend 147 consecutive days on the
Khumbu Glacier. While at base camp, Olech and
Andrzej Heinrich fixed a new route up the southern pillar to the height of 8300m, and established the expedition's highest camp. The Polish expedition would be the first to summit Everest in winter successfully. In 1984, Olech ended his high-altitude mountaineering career at 56 by climbing
Satopanth (7075 m) and
Kedarnath Dome (6831 m) in the
Garhwal Himalayas. In addition to climbing, he served as vice president of the High Mountaineering Club and the Polish Mountaineering Club. After he retired from climbing, he was awarded the Bronze Cross of Merit and received the Polish Gold Medal "For Outstanding Sports Achievements" four times. He additionally received a gold medal for the 100th Anniversary of Polish Alpinism and was named an Honorary Member of the Polish Tatra Society. He is the co-author of:
Kangbachen zdobyty (1977),
Dwie Kangchendzongi (1983), and
