THE STUDY AREAGeographic LocationThe study area comprises an area of approximately 1 .5squaremiles, with dimensions of 2 miles by .75 miles, along thesummit of MountRevelstoke (Figure 1) . This area is located to the northeast of the cityof Revelstoke, British Columbia in Mount Revelstoke National Park . Approximateco-ordinates are lat . 510 03'N and long . 1180 08'W . Included withinthe study area are Heather Lake, Balsam Lakes and the Summit viewpoint .PhysiographyThis is a mountainous area, being part of the medium sized SelkirkMountains . Elevation of the summit ridge is approximately 6,300 to 6,400feet ASL1 and the lowest parts of the study area approach 5,500 feet ASL .Topography of the area is rough, with most slopes being steeply toextremely sloping (15 to 70 percent) (Canada Soil Survey Committee, 1970) .The topography is controlled by the bedrock which outcrops frequently .Bedrock geology of the area has been mapped by the Geologicalsurvey of Canada at a scale of 1 :250,000 (1" = 4 miles) (Geol . Surv . Can .map 12, 1964) . Wheeler (1964) describes the bedrock in the area as beingcomposed of a great variety of metamorphic and granitic rocks .The bedrockis part of the Clachnacudainn Salient structure of the Shuswap MetamorphicComplex . The dominant rocks are hornblende granodiorite-gneiss, andleucogranite . The leucogranite occurs as dikes and as extensive masses .The age of these rocks is not certain but they appear to be of variable age,with the youngest rocks being lower Cambrian (Wheeler, 1964) .We found no1 ASL = Above sea level .
