Detailed Soil Survey of the Mount Revelstoke Summit Area.

39TABLE 4,GUIDES FOR ASSESSING SOIL LIMITATIONS FOR CAMP AREASThis guide applies to soils to be used intensively for tents and the accompanying activities of outdoorliving . It is assumed that little site preparation will be done other than shaping and leveling fortent and parking areas. The soil should be suitable for heavy foot traffic and for limited vehiculartraffic .l Soil suitability for growing and maintaining vegetation is not a part of this guide, exceptas influenced by moisture, but is an important item to consider in the final evaluation of site .ItemsAffectingUse None to SlightDegree of Soil LimitationModerateSevereWetnessRapidly, well and moderatelywell drained soils.Water table below 30"during season of use .Moderately well and imperfectlydrained soils.Water table below 20"during season o£ use.Imperfectly, poorly, andvery poorly drained soils.Water table above 20" duringseason of use .Flooding None .None during season of use .

Most of theseit affects foot trafficability, dust, soiltextures are not applicable to this specific area .4 . Coarse fragments include both gravels and cobbles .5 . Some gravelly soils may be rated as slight if the content of gravel exceeds 20% by only a smallmargin providing (a) the gravel is embedded in the soil matrix, or (b) the fragments are less than3/4 inch in size . See the definition for gravels in the System of Soil Classification for Canada(C .S .S .C ., 1970), pp . 213-214 .6 . Very shallow soils are rated as having a severe soil limitation for rockiness and/or stoniness .See also definitions of rockiness and stoniness in the System of Soil Classification for Canada(C .S .S .C ., 1970), pp . 213-214 .
