Of the 14 tallest mountains with a summit above 8000 meters (the "Eight-thousanders"), Annapurna I is the tenth tallest at 8091 meters, or 26,545 feet. It was also the first of the Eight-thousanders to be summited, accomplished by Frenchman Maurice Herzog and his expedition on June 3, 1950. Because of it's dangerous and technically difficult terrain, Annapurna I is generally considered by many climbers to be the deadliest mountain to climb. Of the nearly 200 successful summits, around 90 have died trying to reach the top, a success-death ratio greater than that of Everest.
