| Abstract | During the summer of 1958, the Northern Building Section of the Division of Building Research undertook the installation of deep ground temperature measuring instruments at Norman Wells to determine more accurately the depth and the long-term performance of permafrost in that area.Two holes (NWB 14 and NWB 16) were drilled at two different locations to depths of about 200 feet and two holes (NWB 15 and NWB 17) were drilled to depths of 10 feet. In each of the four holes, thermocouple cables were installed to measure the ground temperatures at various depths. The experience gained in installing this equipment forms the basis of this report. |
