Perhaps we should define <br /> alluvium. Sand , clay and rocks , etc . deposited by flowing water . <br /> There is alluvium in Coal Basin and east :Muddy Creek drainages . <br /> But these drainages are extremely steep and subject to frequent <br /> scouring . Little or no soil as such exists . The major surface <br /> being rocks , sand and gravel . See also Hydrology Section for <br /> static groundwater measurements showing groundwater table for <br /> the most part at 20 to 25 feet below the surface . <br /> zo <br />
