Campbell's only view of the region before landing was from the Terra Nova. As the ship was well out in the Ross Sea, the coastline would have been below the horizon. From that perspective, he saw a large glacier sweeping diagonally away from the west side Mount Melbourne, and heading south in a series of icefalls. In his diaries, he calls this the Melbourne Glacier. This probably led him to believe the piedmont they were setting out on was the outflow of the ‘Melbourne’ Glacier and possibly other glaciers in the region. Professor David in 1913 named this glacier the Campbell Glacier, and it is referred to as such in documents published after the expedition.
