It was found necessary to auger holes in frozen ground up to 30 inches in diameter and up to 50 feet deep. A Williams Auger, Model LDH 50, was purchased to do this work. It was winterized, then shipped by rail to Fort Churchill, Manitoba. Its use as an operational piece of equipment and the daily record kept of its capabilities and deficiencies is the basis of the report. (Author)
