Spring 1999 season
85 expeditions, of which 59 put someone on the summit. 245 summits (181 by members, 64 by hired staff) and 7 deaths, among 478 members and 84 hired staff recorded.
Summits count member records: someone who summited twice on one expedition counts once, someone on two expeditions in the season counts twice. Claimed (unrecognised) ascents are excluded and disputed ones included, as in the database's own statistics. Hired staff are only recorded when they went above base camp.
