Custom Soil Resource Report <br />Upland <br />An informal, general term for the higher ground of a region, in contrast with a low- <br />lying adjacent area, such as a valley or plain, or for land at a higher elevation than <br />the flood plain or low stream terrace; land above the footslope zone of the hillslope <br />continuum. <br />Valley fill <br />The unconsolidated sediment deposited by any agent (water, wind, ice, or mass <br />wasting) so as to fill or partly fill a valley. <br />Variegation <br />Refers to patterns of contrasting colors assumed to be inherited from the parent <br />material rather than to be the result of poor drainage. <br />Varve <br />A sedimentary layer or a lamina or sequence of laminae deposited in a body of <br />still water within a year. Specifically, a thin pair of graded glaciolacustrine layers <br />seasonally deposited, usually by meltwater streams, in a glacial lake or other body <br />of still water in front of a glacier. <br />Very stony spot (map symbol) <br />A spot where 0.1 to 3.0 percent of the soil surface is covered by rock fragments <br />that are more than 10 inches in diameter in areas where the surface of the <br />surrounding soil is covered by less than 0.01 percent stones. <br />Water bars <br />Smooth, shallow ditches or depressional areas that are excavated at an angle <br />across a sloping road. They are used to reduce the downward velocity of water <br />and divert it off and away from the road surface. Water bars can easily be driven <br />over if constructed properly. <br />Weathering <br />All physical disintegration, chemical decomposition, and biologically induced <br />changes in rocks or other deposits at or near the earth's surface by atmospheric <br />or biologic agents or by circulating surface waters but involving essentially no <br />transport of the altered material. <br />Well graded <br />Refers to soil material consisting of coarse grained particles that are well <br />distributed over a wide range in size or diameter. Such soil normally can be easily <br />increased in density and bearing properties by compaction. Contrasts with poorly <br />graded soil. <br />Wet spot (map symbol) <br />A somewhat poorly drained to very poorly drained area that is at least two drainage <br />classes wetter than the named soils in the surrounding map unit. <br />57 <br />
