VEHICULAR ACCESS TO UNDERSNOW FACILITIES.
Substantial effort is required to produce vehicular access ramps leading to subsurface ice cap facilities and to keep them from filling with drift snow. This report describes a technique for producing, maintaining and closing such ramps and outlines the procedure for covering the ramps, first to the...
