Coarse Grained Soils have more than 50% of their dry <br /> weight retained on a#200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have <br /> less than 50% of their dry weight retained on a#200 sieve;they are principally described as clays if they are plastic, and <br /> silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be <br /> added according to the relative proportions based on grain size. In addition to gradation, coarse-grained soils are defined <br /> on the basis of their in-place relative density and fine-grained soils on the basis of their consistency. <br /> LOCATION AND ELEVATION NOTES <br /> Unless otherwise noted, Latitude and Longitude are approximately determined using a hand-held GPS device.The accuracy <br /> of such devices is variable. Surface elevation data annotated with +/-indicates that no actual topographical survey was <br /> conducted to confirm the surface elevation. Instead,the surface elevation was approximately determined from topographic <br /> maps of the area. <br /> RELATIVE DENSITY OF COARSE-GRAINED SOILS CONSISTENCY OF FINE-GRAINED SOILS <br /> (More than 50%retained on No.200 sieve.)
