The Tibbitt to Contwoyto winter road in the NWT: identification of available data and research needs
Information on the Tibbitt to Contwoyto Winter Road north of Yellowknife was acquired by the author during a three-day field trip in March 2008. The construction and maintenance of this road, most of which is constructed over frozen lakes, is managed by the Joint Venture Management Committee (JVMC)....
