Very low: Less than 0.5 percent Low: 0.5 to 1.0 percent Moderately low: 1.0 to 2.0 percent Moderate: 2.0 to 4.0 percent High: 4.0 to 8.0 percent Very high: More than 8.0 percent Outwash Stratified and sorted sediments (chiefly sand and gravel) removed or “washed out” from a glacier by meltwater streams and deposited in front of or beyond the end moraine or the margin of a glacier. The coarser material is deposited nearer to the ice. Outwash plain An extensive lowland area of coarse textured glaciofluvial material. An outwash plain is commonly smooth; where pitted, it generally is low in relief. Paleoterrace An erosional remnant of a terrace that retains the surface form and alluvial deposits of its origin but was not emplaced by, and commonly does not grade to, a present-day stream or drainage network. Pan A compact, dense layer in a soil that impedes the movement of water and the growth of roots. For example, hardpan, fragipan, claypan, plowpan, and traffic pan. Parent material The unconsolidated organic and mineral material in which soil forms. Peat Unconsolidated material, largely undecomposed organic matter, that has accumulated under excess moisture. (See Fibric soil material.) Ped An individual natural soil aggregate, such as a granule, a prism, or a block. Pedisediment A layer of sediment, eroded from the shoulder and backslope of an erosional slope, that lies on and is being (or was) transported across a gently sloping erosional surface at the foot of a receding hill or mountain slope. Pedon The smallest volume that can be called “a soil.” A pedon is three dimensional and large enough to permit study of all horizons. Its area ranges from about 10 to 100 square feet (1 square meter to 10 square meters), depending on the variability of the soil. Custom Soil Resource Report 51 Index #10
