BYRD STATION SNOW TUNNELS - WALL CLEARING STUDY
Present data on the closure rates in most of the tunnels at New Byrd Station, Antarctica indicates that trimming of the walls to maintain desirable clearances will not be required before Deep Freeze 65. A review of the Byrd Station drawings showed that about 75% of the tunnel wall surfaces will allo...
