Sixty years ago this month, in September 1954, the US Army Corps of Engineers completed its first summer of construction at Camp TUTO, Greenland. Camp TUTO was tucked against the Greenland ice sheet east of Thule Air Base. The gently sloping ice sheet adjacent to the camp, earmarked for vehicle access to the ice sheet interior, was named Thule Take-Off (or TUTO). Over the summer of 1954, some of the one hundred soldiers stationed at Camp TUTO built a gravel road up the first 1500 meters (4700 feet) of TUTO Ramp. Although that got them above the sometimes bare ice and slush of the lower elevation ice sheet melt zone, it still proved difficult to drive over the soft snow of the higher elevation ice sheet accumulation zone.
In official reports, the US Army Corps of Engineers tested “every off-road military vehicle (probably not excepting Hannibal’s elephants)” in the search for a suitable over-snow vehicle. The M29C Weasel, originally designed as an amphibious vehicle late in the Second World War, had proved disappointing in swampy terrain, but exceptionally nimble on the ice sheet. Although the Weasel was out of production even before construction started at Camp TUTO, it became a beloved backbone of US Army logistics on the Greenland ice sheet for almost two decades.
Constructing TUTO Ramp and adopting the Weasel opened up the interior of the Greenland ice sheet for a wide array of military engineering activities, including the construction of ice sheet runways and under-snow stations, as well as civilian science activities, including recovering the first “deep” ice core and wide-ranging snow and accumulation surveys. An auspicious anniversary of a ground-breaking project in applied glaciology!
