Spring 1990 season
39 expeditions, of which 19 put someone on the summit. 91 summits (83 by members, 8 by hired staff) and 5 deaths, among 388 members and 24 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.
