1~ 1 to the Middle Creek Underground Nine portal area; 5) Fish J1, on the east bank of Fish Creek upstream from Energy Tipple No. 3; 6) Fish S2, on the east bank of Fish Creek downstream from Energy Tipple No. 3; and ' 7) Fish 03, on the east bank of Fish Creek near USDA-SEA Caging Station 1003. , The lithologic logs of the auger holes are presented in this Exhi- ' bit in Figure 1, Neutron Yrobe Access Tube Lithologic Logs. As shown, the lithology of the alluvium in the intermittent and perennial streams is predominately clay, underlaid by layers of sand and lenses of gravel a[ the bottom of the channel fill. The alluvium of Foidel, Middle and ' Fish Creek contains all three 11tho1ogies in a graded sequence of clay at the top to gravel at the bottom. The logs from neutron probe access tubes and alluvial monitor wells was used to construct Map 17, Energy Mine No. 3 Stream Channel Cross Sections. The lithology and layering the alluvial deposits, as well as the underlying shale bedrock, is ' graphically depicted on this map. The soil moisture data from each neutron probe access tube are listed in this Exhibit in Table 1, Geophysical Soil Moisture Data. ' Readings were taken with a nuclear gauge at six-inch intervals, and are presented in three units of measurement: 1) PCF, pounds water per cubic foot soil,; 2) g/cc, grams water per cubic centimeter soil; and 3) X vol., percent volume eater by weight. The nuclear gauge vas standar- ' dazed at each location before the readings were taken. Soil moisture conditions, and the extent of the capillary fringe in particular, depend on the lithology and characteristics of the alluvium containing the water table. Clay materials are capable of high moisture retention, while an aggregate has almost no retention capability, be- cause of the difference in porosity of the two materials. Thus, the capillary Eringe in alluvium consisting of clay will extend farther ^ 2u0U
