Field journal crew member Shayne Kolesar of excavation methods, items recovered, features, local environment and weather. Pages 34-44 relate to excavation unit 14 at the Graham 2004 site.
Field journal book 2 by crew chief Tomasin Playford of excavation methods, items recovered, features, local environment and weather. Pages 37 to 49 and 73 to 78 relate to the Graham site.
Archaeological testing began in the Crepeele locale in May 2003. The Casselman survey in the Crepeele locale was directed by Bev Nicholson and James Graham supervised the crew. Crew members were Sarah Graham, Jollana Bishop, Lisa Sonnenburg, Todd Kristensen, Michael Evans, and Emily Ansell.
Scope and Content
The director, field supervisor and some field crew kept daily journals of activities during the survey including: excavation methods, items recovered, features, local environment and weather are noted.
Field journals were scanned in their entirety as one multi-page PDF. However, each journal may contain information that relates to multiple sites or individuals. The entire PDF journal is linked to each file level description with the relevant page numbers indicated in the Scope and Content note.
Radiocarbon date reports have been scanned in multi-page PDF files.
History / Biographical
The North Lauder locale has a long archaeological and geological history that is important for understanding the forces that shaped the region. Archaeological research in the locale shows that the area has been occupied by humans for at least the past 6,500 years. Environmental forces provided an area of diverse resources that attracted early peoples.
Archaeologists from Brandon University have been conducting research in the North Lauder locale that has focused on the Atkinson site, a 6,500 year old hunter-gatherer site and Flintstone Hill.
The geomorphology of the glacial Lake Hind Basin over the past 11,000 years is known primarily through the study of a cut bank along the Souris River. Flintstone Hill contains the most complete stratigraphic record for the post-glacial period on the northern plains. The site has been extensively studied by geoarchaeologists, geologists and paleoenvironmentalists over many years and their findings have contributed to our understanding of the region.
Radiocarbon dates were obtained from the Atkinson site and Flintstone Hill.
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.
