North Lauder Radiocarbon Date report by IsoTrace Laboratory for Atkinson site #TO-10640.
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.
Images of a Prairie City was a photography display of early Brandon circa 1912. The exhibition presented images of Brandon in the years immediately prior to the Great War when the city had moved beyond a pioneer stage and taken on the features of a modern North American urban centre, boasting parks, exhibitions, paved streets, and the latest trends in architecture and transportation.
Custodial History
These photographic images were drawn from the Alfred Fowler collection held at the S.J. McKee Archives. They were used in an exhibit entitled "Images of a Prairie City" in March 2004. The exhibit was located on The Curve Gallery in the John E. Robbins Library and curated by Christy Henry.
Scope and Content
Consists of 21 photographic prints (in frames) used by the Archives.
Notes
Seven photographs and the information page are on display in Student Services, McKenzie Building, Room 102. Six are on dislay in McKenzie Building, Room 117 and two are on display in McKenzie Building, Room 104. The remainder of the display is in storage at RG 6 Brandon University fonds
Series 8: Library Services 8.2, S.J. McKee Archives. The prints stored in the Archives should be handled with great care.
