During the late 1910s and into the 1920s when Beaton had become a quieter area, Gunterman, along with her husband Will worked as travelling cooks in nearby areas. In 1927, the Guntermans home burned down therefore many of her photographs were destroyed. However, a number of glass plate negatives and a few albums were stored elsewhere so they survived. Gunterman died in 1945 and three of her photograph albums are currently in the possession of her grandson, Avery Gunterman. Ron D’Altroy of the Vancouver Public Library became interested in Gunterman's work in 1961 and rediscovered three hundred of her glass plate negatives in Henry Gunterman's attic. After collecting these photographs and gaining permission to keep them, the Vancouver Public Library Board digitized her photographs. Her photographs help to reveal life in the Kootenay region of British Columbia. Gunterman's work continues to gain more attention as it has become more accessible to the public through its digitization. From April 28 to September 3, 2018 her work was displayed alongside Emily Carr's at the Vancouver Art Gallery in an exhibition entitled "Emily Carr in Dialogue with Mattie Gunterman."
