Autumn 1978 season
33 expeditions, of which 17 put someone on the summit. 100 summits (90 by members, 10 by hired staff) and 11 deaths, among 308 members and 31 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.
