After the relief ships had departed late February1968 the old base (Halley I) moved all the scientific equipment and instrument the 2 miles up to the partly completed new base (Halley II).
By this time spring was well on the way and the new base huts had already sunk and been covered with snow (after only 1 year). Thus everything was lowered intot he new scientific huts via shafts and rope pulleys.
