unit descriptions in Part III a limited concept of the map unit can be acquired . Fora complete understanding of the map unit concepts the detailed map unit description s(which will be contained in a separate volume as Appendix E) should be consulted .Also, extensive analytical data are provided in Appendices A through D .Field mapping was done on aerial photographs at a scale of about 1 :25,000 .This information was transferred to a 1 :25,000 map and reduced to 1 :50,000 fo rpublication . The mapping scale was chosen as appropriate to provide the informatio nwhich would assist in solving the problems identified through discussion with Park sCanada personnel . Even at this relatively detailed scale, many site specific question scannot be answered . When considering specific sites smaller than 20 to 30 acres ,on-site examination by a qualified soils specialist is still necessary .When soi Is and vegetation, or other resource information is to be compare dfor interrelationships the most useful correlations are obtained by examining the annotatedaerial photographs (desk copies can be examined by contacting the authors) . Lackof precision in the base maps and problems with accurately transferring the soil an dvegetation lines from the aerial photographs to the base maps makes comparisons of th esoils and vegetation maps inconclusive in some areas .
How to use this repor tThis report is written so that it will not be necessary for the casual reade rto digest it from cover to cover . It should be possible for users to obtain th einformation applicable to their needs with an amount of effort in proportion to th ecomplexity of their problem . How to use this report depends on the questions bein gasked . Perhaps the best way to illustrate some of the ways in which this report ca nbe used is to cite some hypothetical examples .Example 1 . A master planner wishes to gain an overview of the soi Is withi nthe Park . First he should consult the colored map at a scale o f1 :125,000 . Reading the introductory sections of interest in Part Iwill help fill in the background of other resources, and the sectio non soil genesis will help clarify the map concepts . This materia lis of a generalized nature, but not necessarily easily understood .Minimally, at least a passing acquaintance with the Canadia nSystem of Soil Taxonomy is required .Example 2 .Example 3 .A manager may wish to know the landform and slope along a give nsection of a valley . He should locate the valley on one of th efour black and white maps that cover the Park . By referring tothe map symbols and the legend, the information is readily obtained .A manager wishes to assess the soil limitations which would likel yaffect the installation of a septic tank filter field in a given area .He should first locate the site in question on the appropriate blac kand white map and then record the map symbol that applies to th esite . By then turning to Table 67 in Part IV of the report andlocating the map symbol and slope in the left column and readin gacross the lines to "septic tank filter field" the appropriate degre eand kind of limitation can be found (map symbols are placed i nalphabetical order, and landforms are not included because theyare co-varying properties) . Caution : because the map symbo ldoes not suggest any limitation does not mean that there will notbe inclusions of unsuitable soil of less than approximately 2 0acres . Care must still be exercised in choosing the exact locatio nof the . installation . Also the user should read Table 62 . whic hprovides the background assumptions leading to the limitation(s)identified .
