Army Plans Greenland Ice Subway(Editor’s notei The following dispatch was received Tuesday over the Associated Press wires following release of a Drew Pearson report on the proposed Greenland subway.)WASHINGTON, May 5, {ff— The army is experimenting with a subway dug into the ice as a means of travel across Green* land’s eternal Arctic icecap.If the experiment is a success, presumably there would be a network of subways through the700,000 square miles of ice, dozens of feet deep.Experimental tunnels and corridors have been maintained by the army for several years. One goes down to a depth of more than 150 feet.An advance party of 240 men left Ft. Belvoir, Va., recently to conduct additional tests and, experiments to see if subway networks would allow defense forces on strategic Greenland to move about under the icecap instead of trying to overcome virtually impossible arctic surface conditions.First a trench will be plowed 25fort deep and 12 feet wide. This will be covered with frozen blocks of snow to make a subway.One objective of the expedition will be to chart paths fojr the subway system and to build experimental roads and airfields on the snow surface at various points.The engineers will also construct experimental undersnaw storage areas, warehouses, garages and aircraft hangars.Danes ApproveThe Danish government has given its approval for the expedition which will work near Thule, the big U. S. strategic air base on the northern coast of Greenland.The task force is under command of Lt. Col. Elmer Clark, Springfield, Mo.The tunneling experiments will be directed by Dr. Henri Bader, chief scientist of the arxny engineers' snow, ice and permafrost research establishment in Wilmette, 111., who originated the idea.
