| Abstract/Description or Keywords |
The objective of this project was to prepare terrain, slope stability and erosion potential maps as a basis for long term environmental planning, including forest harvesting, in the following three areas: Yalakom River (Retaskit-Peridotite Creeks), Murray Creek, and Pasulko Lake. A brief report for each study area accompanies the terrain and interpretive maps. The Yalakom River area, which is the subject of this report, encompasses about 4600 ha.--- Terrain mapping and interpretations for slope stability and erosion potential were carried out according to provincial standards (Sections 3 and 6). Terrain mapping was done on 1 :15 000 scale colour air photos by air photo interpretation, followed by field checkinp. This mapping supersedes air photo interpretation that accompanied a preliminary report on terrain conditions for proposed cutblocks and road alignments that was prepared for Bruce Hupman (MoF) in Spring 1995. Terrain, slope stability and erosion potential information are presented on 1 :5000 scale map overlays. Attention was focused on forested terrain; alpine areas were mapped on the air photos without interpretations for slope stability or erosion potential.--- This report augments the information that is shown on the maps. It provides a general overview of the physiography of the study area (Section 21, descriptions of terrain mapping methodology and mapping reliability (Section 31, additional information about surficial materials and processes (Sections 4 and 5), and criteria used for interpretations of slope stability and erosion potential (Section 6). Implications and recommendations for forest land management that arise out of this terrain work are discussed in Section 7. |
