Fort Simpson, N.W.T. engineering site information: soil and permafrost conditions

Thirty boreholes were drilled from 18 August to 4 September 1958 at various locations throughout the island on which the town of Fort Simpson, N.W.T. is located. One-third of the boreholes were associated with the construction of a hostel for the Department of Northern Affairs and National Resources...
