Scope and content
The material reflects several facets of John Anderson-Thomson's life in the Northwest Territories, including his geological and surveying business, his and Janet's personal and leisure activities, and his role as commanding officer of No. 7 Company Canadian Rangers, Magistrate and Justice of the Peace, and commissioner on the Great Slave Railway Royal Commission. The records include financial records, correspondence, field notes, survey and reference plans, survey instructions, photographs and scrapbooks, certificates, and articles.
The records have been arranged by the Archivist, usually in topical, then roughly chronological order where the original order was not apparent. File divisions and titles, where apparent, have been mostly retained.
