calcareous rocks in the study area and all the surficial deposits are noncalcareous.Observations made during this study indicate that the area has beenglaciated and the bedrock outcrops generally display a rounded appearancedue to glacial abrasion . A thin veneer (2 - 10') of glacial till is presenton most of the summit area . Local deposits of colluvial debris (talus) arepresent at the base of steep bedrock exposures and accumulations of slopewash and alluvial sediments are found in stream channels and basins .Volcanicash is present in two distinct, separated layers(indicating at leasttwo separate falls)in several of the alluvial sections and over much ofthe area itis probably mixed in with other materials in a less conspicuousmanner .ClimateMeteorological data for the summit area are very limited .Snowdepth studies have been carried out in the area (Files, Mt . Revelstoke N .P .Headquarters) and climatic data were collected at four sites during thesummer of 1973 (Landals and Scotter, in prep .) . Data from stations in thegeneral area are shown in Table 1 .The elevation of Mount RevelstokeSummit (6,360 feet ASL) is comparable to that of the meteorological .stationsat Mount Copeland (6,060 feet ASL) and Fidelity Mountain (6,380 feet ASL)and general climatic conditions should also be similar . It is obvious thatthis is a high snowfall area, the amount of snowfall generally increasingwith elevation .Snowmelt on the Summit is not complete until mid-July andfreezing temperatures and snowfall may occur any day of the year .Theeffect of altitude on temperatures and precipitation may be seen by comparingthe data for the Revelstoke stations (ca . 1,500 feet ASL) with the data for
