Eckenstein joined him later that year, and together they climbed several mountains, including Iztaccihuatl, Popocatepetl, and Colima, the latter of which they had to abandon owing to a volcanic eruption.
艾肯斯顿在这一年较晚的时候加入了他，且他们一起攀登了好几座山，包括伊斯塔西瓦特尔火山（ Iztaccihuatl）、波波卡特佩特火山（Popocatepetl）与科利马火山（Colima），而后者因为一次火山喷发而不得不被他们放弃。
