| Abstract | Douglas Channel is a 100 km long fjord located south of the municipality of Kitimat, in northwest British Columbia. The Loretta Island map area covers Loretta Island and the northern tips of Maitland
and Hawkesbury Islands within Douglas Channel where it meets Sue Channel, Loretta Channel, and Devastation Channel. The distance from Sue Channel through Loretta Channel to Douglas Channel is about 15 km. Mapping of surficial sediments, compilation
of landslide deposits, and preliminary interpretation of bedrock types up to height of land were primarily carried out using British Columbia airphotos dated from 2001, 2003, and 2007 ranging in scales from 1:15 000 to 1:25 000. Older, field-based
mapping by the authors in some isolated parts of the study area was incorporated into this mapping, complemented with additional, reconnaissance-level field observation in 2015 and 2016. |
| Summary | (Plain Language Summary, not published)
This is one of six surficial geology an d landslide inventory maps that cover Douglas Channel. Douglas Channel is a 100-km long fjord located south of
the municipality of Kitimat, in NW British Columbia. The purpose is to provide baseline geoscience information on surface sediments and landslide hazard to decision-makers. |
