Granite
  • LAND USE
  • Granite areas are of limited value for farming
    due to too much acidity and surface water, but
    they provide
  • Good terrain for grouse and for military
    training.
  • Good for reservoirs because they are impermeable
    (water cant get through)
  • Tors and bogs are great tourist attractions
