When stoniness or rockiness classes are not shown, those surface conditions are not present . 3 slope class ; simple (regular), very gently sloping, 2 to 5% slopes (class 3) . Multiple (irregular) slopes having the same limits would have an asterisk (*) after the class number, for example 3*. 2 . RK 1 simplemap unit symbol representing a single land type area; a land type unit of the Rockland land type in which 25°16 or more of the area is composed of limestone or dolomite exposures . 3 . U simple map unit symbol representing a single miscellaneous land area, the area has been significantly altered and consists of built-up urbanland . Compound Map UnitSymbols A mapping convention representing a combination of different land areas within one map delineation . Included may be either two soil landscapes, or a soil landscape and a land type area . Dominant and significant land areas composing the map delineation are identified by position ofthe soil landscape or land type units in the symbol, the first shown representing the dominant area and the second shown the significant area . Examples of compound map unit symbols and an explanation of their components are as follows : 1 . F5-NG4 .0 compound map unit symbol representing R2 .2*-2 two soil landscapes F5 dominant soil landscape and components R2.2* NG4 .0 significant soil landscape and components ; 2 surface stoniness or rockiness is not present 2 . J8-RK2 compound map unit symbol representing a 3*-5* soil landscape and aland type area J8 3* dominant components (soil landscape) ; soil phases, surface stoniness, or surface rockiness are not present _RK2 significant components (land type area) 5* 3 . D3-NG2 compound map unit symbol representing 2 two soil landscapes _D3 dominant soil landscape 2 NG2 significant soil landscape 2 Note Single components shown in the denominator apply to both soil landscape units shown in the numerator. GENERAL DESCRIPTION OF SOIL ASSOCIATIONS, LAND TYPES, AND MISCELLANEOUS LAND UNITS Introduction Soit Association Descriptions The soil legend and the soil association definitions follow those developed for the soil survey ofthe Ottawa Urban Fringe ANSTRUTHER (A) (1) . However, a number of new soil associations were identi- Location and Extent Soils of the Anstruther association fied . These include the Boromee, Goulbourn, Greely, occur mainly in West Carleton Township and the City of Lemieux, Malakoff, Ottawa, Reevecraig, and St . Thomas . Kanata, with the majority occurring on, or in close proximity Also, the Leitrim association definition was broadened to to the ridge of Precambrian bedrock which outcrops north of include the Ellwood association and the Piperville association was renamed Osgoode. A number of other associations were modified to better represent soil variability encountered in this survey. Correlation of the soils of the two surveys is discussed in each association description . Saturated hydraulic conductivity data compiled by Mc- Keague and Topp (35) served as a useful guide in the assessment of the soil moisture characteristics of some of the soil associations . the village of Carp . Approximately 4,200 ha of Anstruther soils were mapped, of which 4,000 ha or 95 QIo were mapped in combination with either soils of other associations or miscellaneous land units . Landform and Topography Anstruther soils consist of a 10 to 50 cm thick veneer of undifferentiated drift material which overlies Precambrian igneous and metamorphic bedrock . Often the thin soil veneer is absent in places and the bedrock is exposed at the surface . Topography is controlled by the hum- Soil taxonomyand pedological class definitions and limits mocky nature of the underlying bedrock . Slopes generally used to describe the soil associations are in accordance with the range from 3 to 9 016, but within map units some areas mayhave Canadian System of Soil Classification (22) and the Canada steeper slopes which may range ashigh as 15% . Soil Information System (24) . Soil Material Anstruther soil materials are moderately A summary key to the soil associations is provided in Fig- coarseto coarse textured and contain aconsiderable amount of ure 16 . granitic material of Precambrian bedrock origin . Material originating from Paleozoic limestone and dolomite bedrock is also present at times but to a much lesser extent . material is usually less than 50 cm . Depth of
