The actual transition may be gradual. No warranty is provided as <br /> to the continuity of soil strata between borings. Logs represent the soil section observed at the boring location on the date of drilling only. <br /> References to plasticity of cohesive soils are based on qualitative field observations and not on quantitative field or laboratory tests. Qualitative <br /> v soil plasticity is noted solely to aid in stratigraphic correlation and is not intended for geotechnical characterization of soils. <br /> BORING LOG LEGEND PLATE <br /> �. <br /> k" KLEI N FELDER FOODMAKER, INC. <br /> 100 E.
