In 1978, the American Women's Himalayan Expedition, a team led by Arlene Blum, became the first United States team to climb Annapurna I. The first summit team, composed of Vera Komarkova and Irene Miller, and Sherpas Mingma Tsering and Chewang Ringjing, reached the top at 3:30 pm on 15 October 1978. The second summit team, Alison Chadwick-Onyszkiewicz and Vera Watson, died during this climb.
