This report is part of a terrain inventory conducted in the Clayoquot Sound area and approximately
200,300 hectares have been mapped (1:20000 scale). The main objective of the terrain inventory was to identify areas prone to
geologic and geomorphic hazards, in particular, landslides, soil erosion, and
sedimentation, as well as identify and characterize terrain conditions associated
with these hazards. Available is a final report, PDF images, and map plotfiles.

This report is part of a terrain inventory conducted in the Clayoquot Sound area.
To date, four years have been spent working on the inventory, and approximately
200,300 hectares have been mapped. It includes a description of the physical environment of the area, mapping
procedures, surficial materials present, terrain hazards identified, classification
systems used, and management concerns for the project area. The maps and this
report may be used to assist in development planning through the identification
of unstable and potentially unstable terrain and sensitive soils prior to road
construction and timber harvesting in an area. - - - - - The main objective of the terrain inventory was to identify areas prone to
geologic and geomorphic hazards, in particular, landslides, soil erosion, and
sedimentation, as well as identify and characterize terrain conditions associated
with these hazards. In addition, in Year Four sensitive soils were identified
according to criteria previously established for the Clayoquot Sound area
(Millard et al. 2002). This information can be used to designate soil reserves in
the area. - - - - - Terrain stability mapping methodology follows the Guidelines and Standards for
Terrain Mapping in British Columbia (Resources Inventory Committee 1996)
and Mapping and Assessing Terrain Stability Guidebook (BC Ministry of Forests
1999). The terrain classification used follows see Terrain Classification Systems
for British Columbia (Howes and Kenk 1997). The following TRIM mapsheets were used: 92F.032-42. - - - - - Available is a final report, PDF images, and map plotfiles.
