North Lauder Radiocarbon Date report by IsoTrace Laboratory for Atkinson II site #TO-11882.
Radiocarbon dating
The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949.
Radiocarbon dating is used to estimate the age of organic remains from archaeological sites. Organic matter has a radioactive form of carbon (C14) that begins to decay upon death. C14 decays at a steady, known rate of a half life of 5,730 years. The technique is useful for material up to 50,000 years. Fluctuations of C14 in the atmosphere can affect results so dates are calibrated against dendrochronology. Radiocarbon dates are calibrated to calendar years.
Dates are reported in radiocarbon years or Before Present. Before Present refers to dates before 1950. The introduction of massive amounts of C14, due to atomic bomb and surface testing of atomic weapons, has widely increased the standard deviation on all dates after A.D. 1700 causing these dates to be unreliable.
Accelerated mass spectrometry can more accurately measure C14 with smaller samples and can date materials to 80,000 years.
Scope and Content
Sub sub series contains radiocarbon dates from: Atkinson site and Flintstone Hill.
Hubert Clayton Weidenhamer was born near Dand, Manitoba in 1926. He was raised in Dand and attended school in the Dand Consolidated School District. Weidenhamer enlisted in the Canadian Army in 1943. He became a member of the Priness Patricia's Canadian Light Infantry. Following training in Canada and England Weidenhamer was sent to Italy. He was badly wounded in battle in mid-September and died of his injuries in November 1944 at age 21. He was buried in the Ancona Military Cemetery, Ancona Italy.
Custodial History
These records were in the possession of Bea Chapin (née Weidenhamer) following their creation in the 1940s until they were donated to the S. J. McKee Archives in January 2011.
Scope and Content
Collection consists of correspondence from Hubert Clayton Weidenhamer to his sister Bea. The letters begin in the spring of 1943. Weidenhamer had enlisted in the Canadian Army in January 1943. His letters detail his induction into miltary life in Fort Garry, Winnipeg and his training experience in Canada, principally at Camp Ipperwash, Lambton County, Ontario. He relates his experience of travels on leave to Detriot. Weidenhamer left Canada from Halifax in late 1943 and arrived in Great Britain in December for additional military training. In England, maintaining his morale, waiting for deployment, and coming to terms with British currency were challenges. Transferred to the Princess Patricia's Canadian Light Infantry, Weidenhamer was deployed to Italy in March 1944. The letters dating from March 1944 to September relate in oblique fashion his's experience of military life on the Italian frontier as the Canadian Army fought its way north - "hard fighting" - and the impact of the war on Italian cities and the countryside. He was "proud" of his conduct in action. Weidenhamer's last letter is dated September 11, 1944.
Collection also includes correspondence on Weidenhamer's behalf from his military Chaplin; two press clippings dealing with his military career, and several facimiles of telegrams and correspondence from the Canadian government officials related to Weidenhamer's death and burial in Italy.
Postcard was donated to the McKee Archives by Allen Drysdale, archivist at Beautiful Plains Archives in October 2011. Drysdale received the postcard as part of a larger donation to his archives.
