In January 1960, my first duty station straight out of US Army Signal School, Ft. Gordon, GA, was to the USAPR&DC at Ft. Belvoir, VA. USAPR&DC? What the heck is that? US Army Polar Research and Development Center. After a few months orientation at Ft. Belvoir, things got interesting.
My first trip to Camp Century, Greenland, was a fascinating experience, as we had Walter Cronkite's film crew tagging along to do a documentary. They wanted to see how the trail on the ice cap was explored and marked, so we brought up the Weasel with the crevasse detector mounted on the front of it. The weasel was a small Jeep-like vehicle on tracks, and it had an angle iron framework mounted on the front with several aluminum dishpan-looking attachments that rode on the snow. A tangle of wires trailed back to the control console in the Weasel, where the operator read the output from the sensors. The Weasel maneuvered off the marked trail a few hundred feet to a known crevasse. The crevasse was a cavern under the snow, invisible from the surface. The film crew documented the Weasel's advance, then the console when the alarms sounded. Then things got a little Hollywood on us. The film crew wanted to show how the crevasse was opened and filled in, so we brought out the dynamite. The charge was set in the middle of the snow bridge over the crevasse, the film crew announced “Rolling!”, and the demolition guy pushed the plunger. There was a big boom, and nothing visible happened. All of the blast went down into the crevasse instead of creating a snow geyser for the camera. Well, that wasn't going to work at all for the film crew, so we had to set a second charge just off the crevasse so they'd have their geyser of snow for that scene.
The Hollywood drama didn't end there, however. When the blade Cat was brought up to start filling the crevasse, the film crew wanted to go down inside and shoot some footage. Heckuva deal, as I'd never expected to be able to see the inside of a crevasse. The blade Cat punched a hole in the snow bridge and pushed enough snow into it to form a steep slope. The crevasse was nearly 100' deep and probably 30' wide. We threw a knotted rope down the hole. One of the film crew members was chosen to “be Cronkite”, because no one would know the difference from behind with a parka and hood. Then they filmed as “Cronkite” descended into the hole. The rest of us followed, not using the rope. Just step out a couple of feet into thin air, drop about 10' and bury up into the powder snow slope. Kick out and do it again until we hit bottom.
The inside of the crevasse was one of the most beautiful things I've ever seen. It was like Carlsbad Caverns done in ice. Stalactites, stalagmites, and columns as far as the eye could see in both directions, all in shades of blue and white as sunlight filtered through the snow above. I hated having to leave, but we had somewhat of a schedule to keep. Getting back up that slope was a whole 'nuther story. The top end of that rope was tied to the blade of the Cat, and we grabbed a knot and hung on as it dragged the rope back out of the hole. My shirt was packed with snow inside and out, as the sleeves funneled the snow straight inside. That part I definitely could have done without, but it was fun in retrospect.
Arriving at Camp Century, I saw large snow blowing machines cutting trenches in the ice/snow. The main trench was up to a mile long, and shorter side trenches intersected it. The snow was being blown up and over the side of the trenches. Then cranes lowered curved corrugated steel roof panels onto ice ledges in the walls, and the loose snow was blown back on top of the roof. The snow in contact with the metal would be heated by the activity in the trench enough to melt and form a solid ice roof, adding strength. Prefabbed barracks buildings were set up in the trenches, forming the basis for the “Camp Century, City Under the Ice” title that Cronkite gave his documentary. The documentary aired, I think, in late 1960.
