Late Holocene coastal landscape evolution of northeastern Graham Island, Queen Charlotte Islands (Haida Gwaii), British Columbia is reconstructed from ca. 9.5 ka to present using surficial geology and geomorphic mapping, light detection and ranging (LiDAR) imagery, high-resolution aerial photographs and dating of coastal deposits using optical stimulation luminescence (OSL) and radiocarbon methods.
The northeastern tip of the Naikoon peninsula on Haida Gwaii retains a surficial geological record of Holocene sea-level regression in the form of relict beach ridges, stabilized foredunes, prograding spits and extensive stabilized parabolic dune systems. Together with Dr. Steve Wolfe (GSC) and Dr. David Huntley (SFU, ret'd), we reconstructed the Holocene coastal landscape of northeastern Graham Island, British Columbia. We combined LiDAR, high-resolution aerial photographs and ground-based geomorphic mapping with radiocarbon and optically stimulated luminescence dating to reconstruct coastal deposits and landforms.
