Connecting Camp Century

Men of the US Army Polar Research and Development Center setting up communications at the temporary camp used during the construction of Camp Century, an Arctic United States military scientific research base in Greenland, June 1959. On the right is an M29 Weasel tracked vehicle. The base is a network of trenches dug out of the snow and ice and lined with corrugated steel arches. Camp Century was later found to be a 'cover project' for Project Iceworm, a secret plan to install nuclear missile launch sites under the Greenland ice sheet. Both Camp Century and Project Iceworm were abandoned in 1967 when it emerged that the Greenland ice was not stable enough for the structures to be viable in the long term.
