BYRD STATION SNOW TUNNELS - SIDE-CUTTING WALL TRIMMER.
To prevent excessive snow-tunnel closure, equipment and techniques were developed for trimming the closure snow from the tunnel walls at Byrd Station, Antarctica. The system developed is satisfactory but time-consuming and laborious. At the present average 2-in./yr rate of closure, the walls must be...
