<br />this area to be regarded as a potential aquifer, <br />2, Ground Hater <br />The occurrence of ground water in the subject tracts is <br />controlled largely by the topography, geologic struc- <br />ture, and permeability of rocks immediately underlying <br />the surface through which recharge must occur, qll <br />three tracts lie on moderate to steeply sloping dip- <br />slopes along the backslope of which beds overlying the <br />Wadge coal are truncated by erosion. Also, these beds <br />often are exposed in the sides of stream valleys out <br />into the dipslope surface. Cround-water recharge, <br />therefore, is limited to the narrow band where beds <br />crop out along the steep backslope of the structure and <br />to downward percolation on the diSlope surface itself. <br />Partly because of low permeability of beds immediately <br />underlying the surface and partly because of the <br />opportunity for drainage of these beds afforded by <br />valleys incised into the dipslope surface, very little <br />ground-water recharge to depth is occurring in these <br />areas. Moreover, normal faulting transverse to the <br />direction of strike and inferred directional permea- <br />bility paralleling the direction of strike apparently <br />greatly retard the movement of ground water down dip. <br />Quantitative ground-water studies undertaken by Energy <br />39 <br />
