| Abstract/Description or Keywords |
This report accompanies maps produced for a terrain stability mapping project completed by Madrone Environmental Services Ltd. for two areas referred to as Albreda and Messiter, located near Blue River in central eastern British Columbia. Mapping of the Albreda and Messiter project areas was completed under contract to BC Timber Sales - Kamloops Business Area.----- Approximately 23,400-hectares were mapped for this project. The main objective of the project was to identify areas prone to geologic and geomorphic hazards, specifically landslides and surface erosion. A six-class terrain stability classification systen was used in which Class V is unstable and Class I is stable. ----- This report includes a description of the physical environment of the areas, mapping procedures, surficial materials present, terrain hazards identified, classification systems used, and management concerns. The maps and this report may be used to assist in development planning through the identification of unstable and potentially unstable terrain prior to road construction and timber harvesting in an area, and through the identification of the location of surficial materials and their properties that may or may not be desirable for development activities.----- The project results are presented as terrain maps and terrain stability maps at a scale of 1:20,000. The maps are based on air photo interpretation together with field checking at Terrain Survey Intensity Level C in operable timbered areas. The maps can be used to plan general road and cutblock locations, to identify surficial material properties and material locations (such as aggregate) for use in development activities, and to indicate where more intensive watershed management is necessary. They should not be used for making site-specific decisions concerning loggin or other development activities.----- Terrain stability mapping methodology follows the Guidelines and standards for Terrain Mapping in British Columbia (Resource 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. Mapsheets include 83D.045,055,065. Biogeoclimatic zones include Interior Cedar Hemlock, Sub Boreal Spruce, Engelmann Spruce-Subalpine Fir, and Alpine Tundra. ---- Dossier 06.0419. - Minor data changes were made to the spatial datasets. Original .e00 files are identified with '-orig' in the file name. terrain stability, landslide, debris flow, erosion, geomorphology, surficial geology |
