John Muir agreed in 1881 to sail aboard the Corwin, whose fruitless mission it was to search for the missing scientific research vessel Jeannette, which itself became icebound while exploring the distant and mysterious Wrangell Land in the higher latitudes of the Arctic. This cruise would afford Muir the opportunity to examine evidence of glaciation along the arctic coastlines of Siberia and Alaska and the harmonious lifestyle of Inuits and Chukchis, which was in the midst of disruption from the intrusions of the civilized South.
