Spring 1998 season
94 expeditions, of which 53 put someone on the summit. 251 summits (185 by members, 66 by hired staff) and 12 deaths, among 652 members and 90 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.
