In descending to the Aletsch Glacier the discoverers of this pass were benighted before they could reach the comparative shelter of the Kaulberg cave, and were forced to pass the night on some exposed rocks at the southern base of the Trugberg, where their position in case of bad weather would have been very critical. The Eggishorn was reached on the following morning about 9 a.m. in about 29 hours trom the Wengern Alp.
