ANTARCTIC OPERATIONS

 

   Operation Deep Freeze was an annual mission supported by the US Army Aviation detachment from 1956 to 1969. 

   Each year, from October to January, Fort Eustis provided helicopter transportation and limited logistical support to geophysical scientists and topographic personnel of the National Science Foundation in Antarctica.  They supported scientific field party activities in remote areas of the South Pole.

The detachment operated under the most unfavorable environmental conditions.  At times, temperatures would fall below -40 degrees F, and strong winds and snowstorms were constant.

    Task Force 43, commanded by the US Navy was responsible for Operation Deep Freeze's logistics, planning, coordination, and support.  Due to the Army's experience in Arctic operations, the Navy requested the Army's help to support the scientists in the Antarctic.

Left, Col Merle R. Dawson (L), a Transportation Corps officer, and two other officers reported to the Deep Freeze staff in 1956 as   technical advisors on trail operations.  Dawson was placed in charge of tractor trains and traverse parties.  Later that year, in his first field mission, he led the first group of men from Fort Eustis into Antarctica.

   Col Merle Dawson and 12 other Transportation Corps members had the mission to survey and build a safe trail across unexplored Antarctic territory. 

   Finding a safe route was important over uncharted lands.  They used an Army vehicle (pictured left), resembling a large spider to detect hidden crevasses.  The team detoured around the crevasses or filled them with snow.

 

    Between 1956 and 1957, the Army mapped a trail 650 miles inland and established Byrd Station.  Byrd Station became a major scientific station and exploration base.  Because of the trail, supplies could be easily transported inland.

   Another trail was built between 1957 and 1958 across the Ross Ice Shelf to McMurdo at a distance of 458 miles in order to evacuate equipment and supplies from Little America V and to replenish supplies to inland scientific stations.

   Another trail was built in 1959-1960 between McMurdo and Marble Point, where surveys were conducted for a commercial airstrip.

   During air reconnaissance operations to establish safe routes for the National Science Foundation parties, Army personnel discovered several new ranges in Sentinel Mountains where helicopter detachments supported a detailed mapping operation.

   From the scientific station at Byrd Station, Army personnel flew scientists in the Hueys to remote and inaccessible areas all over the Antarctic.     Scientists from around the world performed experiments in selected areas of the South Pole.

   In 1961, 10 officers and men led by LT John Greene began testing and evaluating the performance  of two UH-1B Iroquois turbo-driven helicopters on the ice and in severe cold.  Two geological missions - TOPO North and TOPO South - were among their first successes.

    Major Palle Mogensen (L) and Major Merle Dawson appeared in an NBC documentary, "Eleven Against the Ice," in September 1957.  Led by Major Dawson, NBC detailed of the 11 men who trailed the 640 mile safe route across the Antarctic to build Byrd Station.
