(unit 10) are shallow, but the water-holding 

 capacity of that zone is quite high because of 

 a deep zone of fractured and weathered par- 

 ent material. 



All soils were considered well-drained ex- 

 cept units 16 and 18, which were classified as 

 moderate to imperfectly drained and poorly 

 drained, respectively. Most soils were rated 

 "C" in the hydrologic soil group classification 



(Soil Conservation Service) which is described 

 as ranging from silty to silty clay loam having 

 restricted permeability. Only the ridge soils 

 (unit 10) were rated "A," fairly light soils of- 

 fering minimum restriction to downward wa- 

 ter movement, while the poorly drained soils 

 in unit 18 were rated "D." All soils were 

 judged to have a moderate inherent erosion 

 hazard.
