The goal of this paper was to determine and verify dates of construction and modification of the barn, to construct a new long-term reference chronology for the Cave Junction area, to evaluate the validity of using Douglas fir for dendrochronology and to identify the criteria for the tree-ring dating of historic structures within the Pacific Northwest.enCreative Commons BY-NC-ND 4.0-USTerminal Project
