The aim of the first season's depot-laying was to place a series of depots on the Barrier from its edge—Safety Camp—down to 80°S, for use on the polar journey which would begin the following spring. The final depot would be the largest, and would be known as One Ton Depot. The work was to be carried out by 12 men, the eight fittest ponies, and two dog teams; ice conditions prevented the use of the motor sledges.[61]
