It is perhaps worth mentioning that the whole Czechoslovak expedition fell victim to an avalanche at the lake Llangunuco in 1970. All 14 climbers died. Ironically, they were originally planning to climb Mt.McKinley/Denali but it was deemed politically unacceptable by the communist regime (not even two years after Soviet-led military invasion of my country). Huascaran was then an alternative solution. There is a simple monument on the place.
