Spring 1978 season
23 expeditions, of which 12 put someone on the summit. 44 summits (39 by members, 5 by hired staff) and 7 deaths, among 201 members and 25 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.
