Regolith thickness of the Glenorchy area

This layer shows regolith thickness of the Glenorchy Area as part of the Tasmanian Landslide Hazard Map Series, 2005. This information is of particular importance on the hill country to assist the validation of the debris-flow source zones. Most of the information comes from field observations made by the geologists who undertook 1:25 000 geological field mapping of the area, but some data is extracted from external reports.
