The Marie Rumble papers date from 1890 to 2002 and measure 4 linear inches. The papers include materials written by Rumble herself as well as recollections written by Rumble's youngest sister, Pearl Rumble Mirich. Materials written by Rumble include several letters she wrote to her mother and sisters between 1920 and 1945 while living in Wyoming, Colorado, and Washington State. The letters describe many of her hardships, including major surgery she underwent in 1934. Rumble's letters also reveal a deep devotion to her second husband, Jack Achttien. After her sister Edna suffered a miscarriage in 1934, Rumble wrote an impassioned letter sharing some of the pain she had experienced at the stillbirth of her own child over ten years earlier. Also among the correspondence is a letter Jack Achttien wrote to Rumble's mother in 1920, a 1987 letter Edna wrote to her sister Pearl recalling her experience at age seventeen of traveling to Wyoming to help their sister Marie deliver Jack Jr. and a 1987 letter written to Pearl from Carol Farthing, whose family owned the Farthing Ranch. There is also a photocopy of a journal Rumble kept in 1921 in which she describes life on the Wyoming homestead and her adoration for husband, Jack. Two scraps of paper in Rumble's handwriting describe what sister Pearl calls her sister's "philosophy of life."

Pearl Mirich's memories of her oldest sister come in several forms. A Homestead on the Range: A Tenderfoot Girl in Wyoming is a fictionalized manuscript depicting Rumble's life, while "An Account of Marie Rumble's Life and Her Family" is a biographical sketch Mirich wrote in 2002 when she was 92 years old. The Rumble papers also include several handwritten recollections Mirich wrote about the Rumble siblings, including Earl Rumble's death during the 1918 flu epidemic, and about her experiences in Wyoming and Jack Achttien, Jr.'s World War II exploits.

The photographs included in the collection are copies of originals and include photographs of Rumble's parents on their wedding day in 1890 and their fiftieth anniversary in 1950. There are several photographs from Rumble's homesteading years in Wyoming that include photographs of Marie, her husband Jack, her children Jack Jr. and Evelyn, and her sisters Ruth and Pearl Rumble. A detailed description written by Pearl Rumble Mirich is included with each photograph.
