The objective of this journey was geological exploration of the coastal area west of McMurdo Sound, in a region between the McMurdo Dry Valleys and the Koettlitz Glacier.[82] This work was undertaken by a party consisting of Taylor, Debenham, Wright and Edgar Evans. They landed from Terra Nova on 26 January at Butter Point,[lower-alpha 7] opposite Cape Evans on the Victoria Land shore. On 30 January, the party established its main depot in the Ferrar Glacier region, and then conducted explorations and survey work in the Dry Valley and Taylor Glacier areas before moving southwards to the Koettlitz Glacier.
