• Abstract:
  As a part of this study, karst areas of the Hagerstown, Mason Dixon, Williamsport, Clear Spring, and Hedgesville
  
  quadrangles (western half of the Hagerstown Valley) were mapped in detail to determine the distribution of karst
  
  features relative to bedrock geologic units using a global positioning system. More than 2,100 karst features were
  
  identified and located and the following observations were made:
  
   There was a generally identifiable relationship between the type of karst features and the bedrock units.
  
   In addition to bedrock composition, joints, and faults appear to have played important roles in the
  
  development of the karst systems in the study area.
  
   Preliminary findings suggest the impact of human activities on karst development is less pronounced than in
  
  the Frederick Valley.
  
   Unlined drainageways appear to just as frequent culprits in sinkhole activity as they are in the Frederick
  
  Valley. Likewise, areas surrounding quarries and stormwater runoff ponds are common sites of sinkhole
  
  development.
  
  This study illustrates that future development will benefit from the current studies of karst development in the
  
  Hagerstown Valley. Planners can now employ the relative karst susceptibility on the different rock units as a basis
  
  for preliminary examination of areas of the Valley that are underlain by these soluble rocks.
