-44-PARTII IMAP UNIT DESCRIPTION SINTRODUCTIONThe general relationships between the Iandforms and their associated soilscap egroups are discussed in the following section . Information related to specific soilscapegroups and soilscape map units is given in the section entitled Soilscape Grou pDescriptions (page 47 ) . A summary of the soilscape group - Iandform combination sis given in Table 4 . The descriptions are arranged alphabetically for ease of use .LANDFORM-<strong>SOIL</strong>SCAPE GROUP RELATIONSHIP SColluvial Landform sBurgess (BG), Float (FL), Niles (NI), Silverslope (SI) and Otto (00) are th esoilscape groups which are associated with colluvial landforms (Figures 23, 75, 84) .Generally, they occur on colluvial veneers and blankets over bedrock, but colluvia lfans and aprons are also common . The materials are generally calcareous and mediu mtextured, although coarse textured materials may also occur, depending upon th elithology of the colluvial source . Coarse fragment contents vary from nil to abou t90%, and the coarse fragments vary from gravel sized to boulders . The soils characterizingthe Burgess soilscape group are Regosolics while the Float, Niles, Silver -slope and Otto soilscape groups are more stable and are characterized by Brunisoli candPodzolic soils .Fluvial Floodplain Landform sKicking Horse (KH), Otterhead (OT) and Beaverfoot (BC) are the soilscap egroups which are associated with fluvial floodplains (Figures 18, 50,81) . Generallythey occur on level or gently undulating fluvial floodplain deposits but Otterhea dsoilscape groups may occur on fluvial terraces which have not flooded for hundreds o fyears . Fluvial floodplains are found in the valley bottoms of most of the majo rvalleys, especially along the Kicking Horse and Beaverfoot Rivers . The materials
