Viljo Rosvall and Janne Voutilainen, while working to organize lumber workers with the Lumber Workers Industrial Union of Canada (LWIUC) at Onion Lake, disappeared in November 1929 and were later found dead. These deaths have been contested: many believe that they were killed for their work in the labour movement, while the official inquest stated their deaths were accidental and due to drowning.

This collection of records includes academic and popular articles related to the deaths of Rosvall and Voutilainen, and materials related to their grave site and memorials. The most significant item here is an affidavit made by Arthur Alanko to Ernie Epp and Paul Pugh: he states that while visiting Finland in 1990 he was given information about men who had killed Rosvall and Voutilainen and then returned to Finland. This information is new to the story as generally understood and told as part of Thunder Bay's popularly understood history.

Correspondence and papers of the Pigeon River Lumber Company, primarily in the 1930s and 1940s. Includes the original Letters Patent. Many of the records relate to lands in the Township of Pardee.

Note that file 82A also includes a partial Port Arthur voters' list, used as scrap paper.

Consists of a memoir written by Horace Hunter "Holly" Parsons, an aerial timber sketcher whose career spanned over 50 years. This memoir contains information about the contracts he fulfilled for the Ontario Ministry of Natural Resources, formerly the Department of Forests and Lands, and various logging, pulp, and paper corporations. Some contracts also involved mapping out the borders of areas where forest fires had occurred. These contracts spanned across Ontario and parts of Quebec, with a focus on the areas surrounding the District of Thunder Bay. Included in the memoir are personal anecdotes, descriptions of his trips, crew members he worked with over the years, and photographs taken by or given to "Holly" Parsons.

Dates of the memoir and accompanying photographs range 1922-1976.

Horace Hunter "Holly" Parsons (1902-1990) was born in Owen Sound, Ontario and lived in Etobicoke, Ontario. He graduated from the University of Toronto in 1925 with a Bachelor of Science in Forestry.
