37INTERPRETATIONSSoil Properties and Land UseSoils are perhaps the most basic resource to consider when planningland use activities .Proper use and management of soil resources isrequired to accommodate user activities and facilities at minimal cost, bothin terms of construction and maintenance and in terms of the amount ofimpairment to the environment .Soils vary in their type and severity oflimitations as sites for developments such as trails,camping areas,buildings, or septic tank filter fields . Some soils have severe limitationsfor one or more uses, while other soils may be well suited for anumber of uses . Knowledge of soil characteristics is basic to goodplanning and management .This section of the report provides predictions of soil performancebased on field observations and laboratory data as well as pastexperience and published information .These predictions are intended toserve as input into the planning process, not as recommendations for landuse, thereby providing tools for the use of planners .It must be realized that the interpretations are based on thecharacteristics of natural soils to a depth of 1 or 2 meters (3 to 6 feet)(although characteristics at greater depths can often be extrapolatedfrom available information) .Due to the variable nature of soils, smallinclusions of unmappable (due to scale) soil types may be present in anarea where a development is planned .Therefore, on site investigation bya person familiar with soils isrecommended prior to construction offacilities .The following are some of the basic soil properties that singly
or in combination with others commonly affect recreational land use .Thelimitations of these soil properties are summarized in Tables 4 to 9 .Wetness affects bearing strength, compactibility and erodibilityof soils .Wetness may result from proximity to late snowbeds or streams,ponding of runoff water, or groundwater seepage and high water table .Soil properties (and vegetation) reflect the high moisture conditions evenat a time in the year when the soil is dry .Soils that are wet for all, orpart, of the season of use have obvious limitations assites for trails,camping areas or other such uses .Flooding hazard can be predicted from soil properties andlandscape position .Soils that may be flooded during the season of usecannot be used for camping areas or building sites and have limitationsfor uses such as picnic areas and trails .Soil texture may limit the amount and type of use an area issuited to .Properties such as permeability, bearing strength, erodibility,available water capacity and nutrient availability for plant growth areall related to soil texture .In the Mount Revelstoke Summit area highcontents of volcanic ash and sand-sized mica particles have a seriouseffect on soil strength and erodibility .The binding ability of clayandto a lesser degree silt-sized particles are important for soilstability .Generally, medium to moderately coarse textures such as loamor sandy loam are most suitable for recreational uses .The content of gravel, cobbles and stones in a soil may be animportant factor to consider when planning camping areas, trails,orseptic tank filter fields .Slope may cause limitations for use .Steeply sloping areas areseverely limited for use as parking lots or septic tank filter fields,
