Description of the Existing EnvironmentLacustrine material occurs where ice blocks have formed lakes. This material is generally finetextured and is limited in extent. Organic materials also occur in the project area. Theaccumulation of this material requires water to develop so it is frequently found in wet areasaround lakes. Sedge meadows commonly occur in such areas (Plate 6.1-3). Some lakes arelined with boulders and have no vegetation except in the odd crevice between the boulders.Plate 6.1-3. Wet sedge meadow common in depressional areas.There are many creeks in the Project area. Boulders commonly occur on the creek bottoms. Alimited amount of finer fluvial material is associated with the creeks.Glaciofluvial deposits occur along the Hackett River. Such deposits are characterized by verycoarse textured, well sorted sands and gravels. Large eskers, another form of glaciofluvialmaterial, also commonly occur in the project area.6.1.5 TopographyThe topography in the region is low relief with gently rolling, ridges to large, flat areas. Slopesgenerally range from 0% to 7%. Irregular shaped water bodies occur at the base of slopes and indepressions (Plate 6.1-4). These are frequently connected by streams to provide a complexnetwork of water bodies.January 2008 Hackett River Project – Project Proposal Sabina Silver CorporationReport Version B.1 6–7 Rescan Environmental Services Ltd.
