An Attempt to Determine the Age of Timbers from Fort Edmonton, Alberta, Canada
Presented by Mr. James DICKENSON on 15 May 2013 from 18:00 to 21:00

Session: Poster Session + Reception

A historic barn near Edmonton, Alberta, is thought to have contained extant timbers from Fort Edmonton, the Hudson Bay Trading Post constructed in 1795 and dismantled in 1915. When the barn was demolished a few years ago, the Alberta Royal Museum salvaged and archived these timbers. In 2012, they contracted the University of Regina Tree-Ring Lab to determine the age of the timbers, as further evidence that they were derived from Fort Edmonton. This poster describes the results of this project, our approach, and the constraints on our use of standard crossdating methods, including some short and complacent undated ring-width series and the absence of an existing tree-ring chronology from the immediate vicinity. Despite these constraints, we were able to confirm the antiquity of the timbers; crossdating with 11 chronologies from west-central Alberta gave dates in the 18th and 19th centuries, during which the Fort was constructed and rebuilt.
